Question

Which linear equation represents the graph?

A) y = 3x + 6
B) y = 3x − 6
C) y = −3x + 6
D) y = −3x − 6

Answer 1

D) y = −3x − 6

Explanation:

The line passes through the y-axis at -6 meaning the y-intercept (b) is -6

The line goes down 3 and over 1, meaning the slope (m) is -3/1 which simplifies to -3

The equation for a linear line is y = mx + b so plug in -3 for m and -6 for b to get

y = -3x - 6

Answer 2

D) y = -3x - 6
