add 80x to get y by its self then t will be 5y=80x+10 then you divide 5 by everything and you get y=16x+5 the you graph 
You must have the equation in y=mx+b. The m indicates the slope and the b indicates the y-intercept.

80x+5y=10
-80x -80x

5y=-80x+10 *divided by 5*

y= -8x+2

Your y-intercept is 2.
