Write equations for the vertical and horizontal lines passing through the point (−6, -2)
vertical line:
horizontal line:
Answer:
Vertical line: x = -6
Horizontal line y = -2
Step-by-step explanation:
A vertical line will have a constant x value for all values of y so it will be of the form x = k where k is a constant. Since it passes through (-6,-2), where the x value is -6, we get the equation x = -6
A horizontal line will have a constant y value for all values of x so it will be of the form y = k where k is a constant. Since it passes through (-6,-2), where the y value is -2, we get the equation y = -2
The attached graph shows the two lines and the point (-6, -2)

Answer:
-7/12
Step-by-step explanation:
Please help! State which property of equality justifies the statement:
If VR+TY=EN+TY, then VR=EN.
The subtraction property of equality is the property of equality that validates the statement "If VR + TY = EN + TY, then VR = EN." This assertion is expressed in the form of "If VR + TY = EN + TY, then VR = EN."
How can one identify whether a feature of equality warrants the assertion being made?VR + TY = EN + TY
Therefore
VR=EN
The following equation results from using the equality property's subtraction property.
Thus, we have
VR + TY - TY = EN + TY - TY
Determine the difference in the aforementioned equation.
Thus, we have
VR = EN
Hence, If VR + TY = EN + TY, then VR = EN is supported by the equality's subtraction feature, which is stated as "If VR + TY = EN + TY, then VR = EN."

Find the gradient of the line segment between the points (5,-2) and (3,-8).
Answer:
3
Step-by-step explanation:
The gradient of the line can be calculated using the [tex]\frac{rise}{run}[/tex] between two points.
[tex]\frac{rise}{run}[/tex] = [tex]\frac{-8-(-2)}{3-5}[/tex]
= [tex]\frac{-8+2}{3-5}[/tex]

Determine the intercepts of the line
Answer:
x-int: (-40, 0)
y-int: (0, 15)
General Formulas and Concepts:
Algebra I
The x-intercept is the x value when y = 0. Another way to reword that is when the graph crosses the x-axis. The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.Step-by-step explanation:
According to the line on the graph, it passes the x-axis at x = -40 and it passes the y-axis at y = 15.
Therefore, our x-int is (-40, 0) and our y-int is (0, 15)
Reflect over the x-axis, and then dilate
by a scale factor of 2.
(0, -4) (-2,-4)
(-1,-7) (1, -7)
When reflected over the x-axis and then dilated by a scale factor of 2 the points become (0,8), (-4,8), (-2,14) and (2,14). We need to know about reflection about axes and dilation.
When a point is reflected about the x-axis the x-coordinate remains same but the sign of the y-coordinate changes.When a point is reflected about the y-axis the sign of the x-coordinate changes while the y-coordinate remains same.When a point is reflected about the origin the sign of both the x-coordinate and the y-coordinate changes. Dilating a figure means changing it's shape or size by a scaling factor, the points are multiplied by the corresponding scaling factor. In this question we have to reflect the points about x-axis and dilate by a scale factor of 2. When the points will be reflected about the x-axis the new points will be (0,4) , (-2,4) , (-1,7) and (1,7). Then we have to dilate by a factor of 2, the final points will be (0,8), (-4,8) ,(-2,14) and (2,14).
After reflecting over x-axis and then dilating by a scale factor of 2 the points (0,-4), (-2,-4), (-1,-7) and (1,-7) become (0,8), (-4,8), (-2,14) and (2,14).

Help!!! Will give brainliest!!
the sum of three angles of a triangle adds up to 180 degrees. In this problem, you are given two angles.
x+(2x+15)+the measure of angle Q should equal 180.
Since everything is addition, the parenthesis can be removed.
x+2x+15+Q=180. This can then be simplified to 2x+15+Q=180. Subtract 15 from both sides to get 2x+Q=165. Divide both sides by two to get the x by itself. x+Q=82.5.

Kayden is a stunt driver. One time, during a gig where she escaped from a building about to explode(!), she drove at a constant speed to get to the safe zone that was 160 meters away. After 3 seconds of driving, she was 85 meters away from the safe zone.
Let y represent the distance (in meters) from the safe zone after x seconds.
Which of the following could be a graph of the relationship?
The graph that could represent the relationship between distance and time is: Graph C.
How to Interpret the Graph of a Relationship?A graph is usually plotted to have the independent variable on the x-axis and the dependent variable on the y-axis. For example, tin the scenario given, distance is plotted on the y-axis, while time is plotted on the x-axis.
The slope of a graph declines if the initial value decreases or if the slope value is negative and reduces.
In this scenario given, the starting value/initial value is 160 meters. After 3 seconds of driving, the initial value/starting value decreases to 85 meters.
This implies that the slope of the graph is declining from left to right. Therefore, the graph that could represent the relationship between distance and time is: Graph C.

in graphing what would be x and y? 0.2(1)=0.5(1-6)
In graphing x is the value on the x axis and y is the values that represent values on y axis.
Given nothing but we are required to tell what x symbolises and y symbolises in graphing.
A graph is basically a common data structure that consists of a finite set of nodes and a set of edges connecting them.
There are coordinates which are written as (x,y) where x symbolises the values on x axis and y represents the values on y axis.
Suppose the coordinate is (2,3). In this we have to plot a point equal to x=2 and then a point equal to 3.Now take one line from both the points straight and the point where they meet will be (2,3).
Hence in graphing x is the value on the x axis and y is the values that represent values on y axis.

A car dealer is calculating the list price for a used car. The dealer takes the initial price of the car and adds $259 dollars for cleaning and shipping the car to the dealer. The dealer then increases that price by 25% for the dealer’s profit. That price is then increased again by 10% for the salesperson’s commission. If a used car is initially priced $10,000, what will be the list price for this car?
Add the 259 to the initial price:
10,000 + 259 = 10,259
Increase that price by 25%, so multiply by 1.25:
10259 x 1.25 = 12,823.75
The price is then increased by another 10%, multiply by 1.10:
12,823.75 x 1.10 = 14,106.13
List price = $14,106.13
