Hey!

-------------------------------------------------

Point Slope Form: y - 7 = -5/2(x + 4)

Slope-intercept Form: y = mx + b

m = slope

b = y-intercept

We can automatically eliminate Option A and B because they are both written in point slope form when the questions asks for slope-intercept form.

We can also eliminate option C because the slope in the equation doesn't match the slope in the equation above.

-------------------------------------------------

Answer:

y = -5/2x - 3

-------------------------------------------------

Hope This Helped! Good Luck!
