Write the Slope-Intercept and Point-Slope forms of the line passing through the point (-3, 2) and having a slope of -4/5
Answer:
slope-intercept: [tex]y=\frac{-4}{5} x-\frac{2}{5}[/tex]
point-slope: [tex]y-2=\frac{-4}{5} (x+3)[/tex]
Step-by-step explanation:
The slope-intercept form of a line is written as y = mx + b, where m is the slope and b is the y-intercept.
The point-slope form of a line is written as y - y1 = m(x - x1), where (x1, y1) is a given point and m is the slope.
Here, we see that the slope is -4/5, which means that m = -4/5. Since we're given a point (-3, 2), let's go ahead and just write the point-slope form already. (x1, y1) = (-3, 2) so x1 = -3 and y1 = 2. Then:
y - y1 = m(x - x1)
y - 2 = (-4/5) * (x + 3)
[tex]y-2=\frac{-4}{5} (x+3)[/tex]
Now, we want to find the slope-intercept form, so we need to figure out the y-intercept. Well, first, let's plug in what we know:
y = mx + b
y = (-4/5)x + b
Any point on this line will satisfy the above equation. Since (-3, 2) is on this line, if we plug -3 in for x and 2 in for y, the equation should hold true, so we can solve for b:
y = (-4/5)x + b
2 = (-4/5) * (-3) + b
2 = 12/5 + b
b = -2/5
So, the y-intercept is -2/5. Then the slope-intercept form is:
[tex]y=\frac{-4}{5} x-\frac{2}{5}[/tex]
Thus, our two equations are:
slope-intercept: [tex]y=\frac{-4}{5} x-\frac{2}{5}[/tex]
point-slope: [tex]y-2=\frac{-4}{5} (x+3)[/tex]

What is the slope of the line? Please explain your answer.
A.) m=5
B.) m= -5
C.) m=1/5
D.) m= -1/5
Answer: D
Step-by-step explanation: Assuming the left point is A at (-2,2) and the right point is B at (3,1) we can determine the slope by using the “Rise over Run” rule where the change in Y is the “Rise” and the change in X is the “Run”. By setting up the equation y2-y1/x2-x1 we can plug in the coordinates from the variables and get 1-2/3+2 which leaves us with our answer m= -1/5

Doug and Emily are driving cars on a track, and they both do 20 laps around a 1-mile track. Doug drives an average of 60 miles per hour around the track while Emily drives at an average of 80 miles per hour. When Emily finished her 20 laps how many laps does Doug have left?
Answer:
When Emily finishes 20 laps Doug has to finish 5 laps.
Step-by-step explanation:
To find how many laps does Doug have left, we need to calculate the time that Emily takes to finish 20 laps:
[tex] t = \frac{x}{v} [/tex]
Where:
x: is the distance = 1 mile
t: is the time
v: is the speed of Emily = 80 mi/h
The time that takes Emily to do 20 laps is:
[tex] t = 20*\frac{1 mile}{80 mile/h} = 0.25 h [/tex]
Now, we can find the number of laps:
[tex]x = v*t = 60 miles/h*0.25 h = 15 miles*\frac{1 lap}{1 mile} = 15 laps[/tex]
[tex] laps = 20 - 15 = 5 [/tex]
Therefore, when Emily finishes 20 laps Doug has to finish 5 laps.

all you have to do is see the difference, imma make a table here first
x y
1 10
3 24
6 45
11 80
15 108
from 10 to 24 you add 14
from 1 to 3 you add 2
so y/x
14/ 2 = 7
check:
from 24 to 45 you add 21
from 3 to 6 you add 3
so y/x
21/3 = 7
From y/x your final answer will always be 7.
So the rate of change will be 7.

What is the x and y intercept absolute min/max
x and y-intercept :
The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations.
Absolute min:
An absolute maximum point is a point where the function obtains its greatest possible value.
Absolute max :
An absolute minimum point is a point where the function obtains its least possible value.
Local Extrema (Local Maxima/Minima): The local maxima and minima on a graph refer to the maximum and minimum points of the graph over a specific interval of the graph as opposed to the entire graph, so there can be multiple local maxima and minima of a given graph.
When considering which points are the absolute maximum and the absolute minimum of a graph, we not only need to consider local extrema (a maximum/minimum of a graph on some interval that contains the point), but we also need to consider the endpoints (the furthest left/right points on our graph). By looking at the y-values for each of these points, we can identify the absolute maximum of the graph as the point with the highest y-value, and we can identify the absolute minimum as the point with the lowest y-value.
Step 1: Identify local maxima/minima, as well as the endpoints.
From this graph, we can see that our graph is on the interval
This means we have our endpoints at [-1,-1] , [4,1] ,
to consider. We also observe that we have one local minima and one local maxima in between these points on our interval. The estimated points are all shown in the image.
absolute minimum point : [-1,-1]

Step-by-step explanation:
In 40 minutes; diane walks 2.5 miles and sue walks 1.5 miles. in miles per hour , how much far diane walking?
Diane will walk 1.5 miles more than Sue.
Firstly calculating the speed of Diane and Sue in miles per hour. As per the known fact, 1 hour has 60 minutes.
In 40 minutes Diane walks distance = 2.5 miles
So, converting speed in miles per hour = (2.5 ÷ 40)×60
Speed of Diane in miles per hour = 3.75 miles per hour
In 40 minutes Sue walks distance = 1.5 miles
So, converting speed in miles per hour = (1.5 ÷ 40)×60
Speed of Sue in miles per hour = 2.25 miles per hour
Difference between the distance covered = 3.75 - 2.25
Performing subtraction
Difference between the distance covered = 1.5 miles
Hence, Diane will walk 1.5 miles more than Sue.

The Johnson party had a good hunt. They bagged a total of 26 deer which included some
big bucks, little bucks and some does. The number of does is 5 more than twice the amount of
little bucks. The number of big bucks was half as many as little bucks. How many big bucks,
little bucks and does did the party get?
9514 1404 393
Answer:
3 big bucks6 little bucks17 doesStep-by-step explanation:
Let B, L, D represent the numbers of big bucks, little bucks, and does, respectively.
B + L + D = 26 . . . . . . total bagged
D = 5 + 2L . . . . . . . . . 5 more does than twice the number of little bucks
B = L/2 . . . . . . . . . . . . half as many big bucks as little bucks
__
We can substitute for B and D in the first equation:
L/2 + L + (5 +2L) = 26
7/2L = 21 . . . . . . . . . . . . . subtract 5, collect terms
L = 6 . . . . . . . . . . . . . . . . . multiply by 2/7
D = 5 + 2·6 = 17
B = 6/2 = 3
The party bagged 3 big bucks, 6 little bucks and 17 does.
