Which equation has the steepest graph?

A. y = x + 3

B. y = - 7x + 7

C. y = 3x + 1

D. y = 5x - 2

Each equation is in y = mx+b form (slope intercept form)

The m is the slope. It is the number just to the left of the x

y = x+3 is the same as y = 1x+3 since 1*x = x

The slopes for A, B, C, and D are: 1, - 7, 3, and 5 respectively

The value - 7 is furthest away from zero on the number line. So y = - 7x+7 has the steepest graph

Answer: Choice B)
