Slope-Intercept Form

Which is the graph of the line with slope -1/2 and y-intercept -3?

Find the equation of the line that passes through the points (-5, 2) and (1, 8).

• y = x + 7

• y = x - 7

• y = -5x + 2

• y = 5x + 2

You have already saved $75 toward the cost of a new phone. You plan to save $10 more per week for the next several weeks. Which equation represents the total amount of money, T, that you will have saved w weeks from now?

• w = 10T + 75

• T = 10w + 75

• w = 75T + 10

• T = 75w + 10

Select the equation of the line that passes through the point (1, 5) and has slope 2.

• y = 3x + 2

• y = 2x + 5

• y = 2x + 3

• y = 2x - 5
