Question

What is the slope and y-intercept of this line?

y=−12x+7

slope: 12, y-intercept: −7

slope: −7, y-intercept: −12

slope: −12, y-intercept: 7


slope: 7, y-intercept: −12

Answer 1

(c) slope: -12, y-intercept: 7

Explanation:

The given equation is in the slope-intercept form:

y = mx +b

In this form, m is the slope, and b is the y-intercept.

__

Comparing the given equation to the form, we see ...

y = mx +b

y = -12x +7 ⇒ m = -12, b = 7

The slope is -12; the y-intercept is 7.
