$slope\ is\ for\ y=0\\\\
y=2,5x+5\\
0=2,5x+5\ \ \ | subtract\ 5\\
-5=2,5x \ \ \ | divide\ by\ 2,5\\
x=-2 ---> SLOPE\\\\\
intercept\ is\ for\ x=0\\\\
y=5----> INTERCEPT$

If you are solving for x.
y=2.5x+5
you subtract 5 from both sides.
-5=2.5x
then divide both sides with 2.5
-5/2.5 2.5/2.5
the 2.5s will cancel each other out.
x=-2
