Find the value of y if the line through the two given points is to have the indicated slope.

(-5,y) and (-6,1) m=-2

Respuesta :

slope is the change in y/ change in x so the equation will be:
-2= (1-y)/(-6-(-5)) -> simplify -> -2= 1-y/-1 -> multiply both sides by -1 -> 2=1-y -> simplify and -y= 1 -> y=-1
