Solved Example on Graph

Identify the graph of the equation whose slope is - 3 and y-intercept is 6.

Choices:

A. Graph 2

B. Graph 3

C. Graph 1

D. Graph 4

Correct Answer: C

Solution:

Step 1: The equation of the line with slope – 3 and y-intercept 6 is y = - 3x + 6 which is 3x + y - 6 = 0.

Step 2: So, The graph for the equation is Graph 1.
