Solved Example on Graph
Identify the graph of the equation whose slope is - 3 and y-intercept is 6.
A. Graph 2
B. Graph 3
C. Graph 1
D. Graph 4
Correct Answer: C
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.
