MULTIPLE CHOICE

1. ANS: D

Plot the y-intercept –3 on the graph at (0, –3). The slope is −1

2, so from the y-intercept, rise –1 units and run 2

units. Plot another point. Connect the points to graph the line.

Feedback

A The y-intercept should lie on the y-axis.

B Slope is rise over run.

C In the form y = mx + b, m is the slope and b is the y-intercept.

D Correct!

2. ANS: C

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Substituting 2 for the

slope and 3

2 for the y-intercept gives y = 2x +
