Graphing Linear Equations

What is the correct equation?

• x = 5

• y = 5

• x = - 5

• y = -5 

What is the correct equation in
Slope-Intercept Form?
(y = mx +b)

• y = -1/3x + 3

• y = 1/3x - 3

• y = -1/3x - 3

• y = 1/3x + 3 

Bob has $150 in his savings account and saves $40 per month.

• y=150 + 40

• y=40x + 150

• y=150x + 40

Bob has $150 in his savings account and saves $40 per month.  Which equation represents the amount Bob has in his account after x months?

• y = 150 + 40

• y = 40x + 150

• y = 150x + 40

What is the y-intercept of the line?

• (0, 1/2)

• (0, 1)

• (0, -1/2)

• (0, -1)

The point where the line crosses the y-axis is called the:

• origin

• x-intercept

• y-intercept

• slope
