The point-slope form:

[tex]y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (-16, 8) and (4, -2). Substitute:

[tex]m=\dfrac{-2-8}{4-(-16)}=\dfrac{-10}{20}=-\dfrac{1}{2}\\\\y-(-2)=-\dfrac{1}{2}(x-4)\\\\\boxed{y+2=-\dfrac{1}{2}(x-4)}[/tex]

The slope of the line =rise / run

= (8- -2) / (-16-4)

= 10/ -20

= -1/2

the  point-slope form is y - y1 = m(x - x1)    so plugging in m = -1/2 and the point (4 , -2) we have:-

y + 2 = -1/2(x - 4)  (answer)
