Question

Identify the graphed linear equation.
A) y = 5x + 2
B) y = 5x - 2
C) y = -5x + 2
D) y = -5x - 2

Answer 1

D
It is because the slope is negative and the y intercept is -2

Answer 2

The y-intercept is -2, which gives you the b of the slope-intercept form (y=mx + b). This would rule out choices A and C. It rises 5 and goes to the left 1 in the negative direction. This gives you the m part (rise/run). This would give you the answer of:

D) y = -5x - 2
