Module 12

Relationships in two variables

You should have these notes already in your notebook. Please rewatch the lesson to refresh yourself on this skill. The video is in the next slide.

Now you should be ready for some practice slides.

To graph a point on the coordinate plane, you will begin at zero, zero and then graph the x coordinate before you graph the y coordinate.

Multiple Choice

Which point is located at (-2, 3)

• Point S

• Point F

• Point G

• Point H

Multiple Choice

What are the coordinates of point S?

• (-2, 2)

• (2, -2)

• (2, 0)

• (2, 2)

Multiple Choice

Which points are on the axes?

• E and S

• E and F

• P and H

• P and E

The independent variable will always be the x value or the x label and the dependent variable will always be the y value or the y label.

Multiple Choice

The table shows a bicycle rider moving at a constant rate of speed. What is the dependent variable in this situation?

• rate

• time

• speed

• distance

When you write an equation the represents the table, you will always begin that equation with a y equals and then state what happens to the x.

Ask yourself what is happening to the x? Is it increasing or decreasing? If it's increasing, it can only be addition or multiplication. If it's decreasing it can only be division or subtraction.

Multiple Choice

• A

• B

• C

• D

Multiple Choice

• y = 2x

• y = 50x

• y = x + 98

• y = 400 + 8x

Multiple Choice

What is the solution to the inequality below?

8m  $\ge$  40

• m $\ge$  5

• m $\le$   32

• m $\ge$  32

• m $\le$  5
