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

Respuesta :

Answer:

  (c)  slope: -12, y-intercept: 7

Step-by-step 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.
