The point slope form of a line that has a slope of -2 and passes through point (5,-2) is shown below.
What is the equation in slope-intercept form?

A. y = -2x + 12
B. y= -2x +8
C. y = -2x -7
D. y = -2x -3

Respuesta :

Insert the point, (5,-2) with the slope of the line to figure out the equation. You can either use point-slope form, or plug it for for slope-intercept form.

Slope-intercept form:
-2 = -2(5) + b
-2 = -10 + b
Add 10 on both sides
8 = b

Thus,

y = -2x + 8

Answer is B
