Question 1

Given the equation $$x = 8$$, what type of line does this equation represent on the coordinate plane?

Accepted Answer

A vertical line

Question 2

Which of the following is the correct solution for $$5x - 8y = -24$$ when $$x = 0$$?

Accepted Answer

$$y = -3$$

Question 3

If $$x = 8$$, what is the value of $$y in $$the equation $$5x - 8y = -24$$?

Accepted Answer

$$y = 7$$

Question 4

Which equation below will always produce a horizontal line on the coordinate plane?

Accepted Answer

$$y = -2$$

Question 5

A printer charges a setup fee of $$\8.50$ and $$\$$0.05$$ for each poster printed. Which equation models the total cost $$y$$ for $$x$$ posters?

Accepted Answer

$$y = 0.05x + 8.50$$

Question 6

If you want to spend no more than $$\24$ on posters, and the cost equation is y = 0.05x + 8.50$, what is the maximum number of posters you can buy?

Accepted Answer

$$x = 500$$

Question 7

Which of the following points is a solution to $$5x - 8y = -24$$?

Accepted Answer

$$(0, -3)$$

Question 8

What is the $$y-$$intercept of the equation $$5x - 8y = -24$$?

Accepted Answer

$$(0, -3)$$

Question 9

Which of the following best describes the graph of $$y = -2$$?

Accepted Answer

A horizontal line crossing the $$y-$$axis at $$y = -2$$

Question 10

If the printer increases the setup fee to $$\10$ but keeps the per-poster cost at $$\$$0.05$$, what is the new equation for the total cost $$y$$ for $$x$$ posters?

Accepted Answer

$$y = 0.05x + 10$$

Question 11

Which quadrant would the point $$(-2, 3) be $$located in on the coordinate plane?

Accepted Answer

Quadrant II

Question 12

If $$x = 0 in $$the equation $$y = -2$$, what is the value of $$y$$?

Accepted Answer

$$y = -2$$

Question 13

Which of the following equations represents a vertical line?

Accepted Answer

$$x = 4$$

Question 14

If you solve $$5x - 8y = -24$$ for $$y in $$terms of $$x$$, what is the resulting equation?

Accepted Answer

$$y = \frac{5x + 24}{8}$$

Question 15

A student claims that the equation $$x = 8$$ passes through the point $$(8, 0). Is $$this correct?

Accepted Answer

Yes, because $$x = 8$$ for all $$y$$
