Slope of a line?

Question

Find the value of y so the slope of the line passing through points (-8, -2) and (4, y) will be 0.

Answer 1

yes it would
if the slope is 0 then
[(y--2)/(4--8)]=0

then you cross multiply and get
[y--2]=0
which is the same as

[y+2]=0
then you move 2 to the other side of the equal sign by subtracting it from both sides of the equal sign like this
[y+2]=0
-2 -2

and you get
y= -2

just like you said
god job!

Answer 2

A line with a slope of 0 is horizontal. That means all y-values are the same. So if one point is (-8, -2) then the other point must be (4, -2) and the equation of the line passing through both is: y = -2
