Find the slope of each line.

Answers

To find the slope of a line, remember:

[tex]slope=\frac{rise}{run}[/tex].

Also, the points that you choose to use to calculate your rise and your run must meet at an exact point, not in the middle of a block. In your graphs the points are the little blue dots, so that's already been done for you and that's what we'll use to calculate the slope!

Also, recall that the rise is how many blocks the line has changed vertically (so is one point lower/higher than another point)

The run is how many blocks the line has changed horizontally (so how many blocks over is the next point)

Therefore, for #1 we can see that the point on the right is over 3 blocks (run), and it goes down 1 block (rise).

So for #1, your answer is: [tex]slope=\frac{rise}{run}=\frac{-1}{3}[/tex] or [tex]-\frac{1}{3}[/tex]

For #2 we see that one point is higher by 3 blocks (rise) and it also goes over one block (run)

So, your answer to #2 is: [tex]slope=\frac{rise}{run}=\frac{3}{1}=3[/tex]

What is the equation of the line parallel to y = -5x + 6 and passes through the point (6,-8)?

Answers

Answer:

y = -5x + 22 is the equation of our parallel line

Step-by-step explanation:

remember a parallel line will have the same slope.

So let's begin by using the equation above and substituting the points.

[tex]y = - 5x + b \\ - 8 = - 5(6) + b \\ - 8 = - 30 + b \\ 30 - 8 = b \\ b = 22[/tex]

therefore our parallel line would be

[tex]y = - 5x + 22[/tex]

Using the line of random numbers to run one simulation,
what proportion of students tried out for a sport?
O 0.40
A study reported that about 40% of high school students
have tried out for a sport at their school. To find out if this
applies to Jessica's school, she surveyed an SRS of 20
students. Nine of them said that they had tried out for a
sport. To see if this result is surprising, a simulation is to
be conducted to estimate the probability of obtaining a
sample result as high as this one.
Let 0-3 represent students who tried out for a sport and
4-9 represent students who did not try out for a sport.

8/total #of people (20) =.4

Using the line of random numbers to run one simulation, the proportion of students that tried out for a sport is .4

Calculation and Parameters:

Given that 40% of students tried out for a sport in a school

The survey is an SRS of 20 students.

Hence, to find the proportion of students that tried out for a sport with the use of a line of random numbers would be:

52644523488246266233

Where # is the number of people trying out is 8

Therefore,

A student wrote a photography manual which she plans to sell online for $ 13 per copy. Her total expenses were $ 55. Write a linear equation to show the relationship between x , the number of manuals the student sells, and y , the profit the student earns.

Answers

Answer:

y = 13x - 55

Step-by-step explanation:

So this is what we know

Selling price = $13 per copy

Expenses = $55

The formula for profit in this case is:

Profit = total selling price - expenses

In which y is the profit

The total selling price is 13x. x here is for the number of manuals she sells

The expenses are $55.

This then becomes y =13x - 55

How can I find 75% of any number?

Answers

Answer:

75% can be converted into a decimal, any percentage can.

Once converted, 75% is actually .75

At this point you can move the decimal place two place up, and put it over 100, in a fractal form

75/100

You can then simplify this to

3/4

You can then use this fraction as a conversion factor with any number, for example if we took the number 8

8∗3/4

2∗3/1=6

Divide it into 75 groups
