Hi!
We need to isolate y on one side. Whatever we do to the equation we have to do to both sides.
-------------------------------------
Subtract 2x from both sides.
2x - 2x - 4y = -2x + 10
-4y = -2x + 10
Divide by -4 on both sides
-4y/-4 = -2x/-4 + 10/-4
y = 1/2x - 2.5
--------------------------------------
The slope is 1/2
Hope this helps! :)
