Solve equation for Y and graph it.

5y-x=20

How do I go about solving and graphing this equation.

Let's worry about graphing this first: 5y-x=20

If you set x = 0, then y = 4, and the y-intercept is then (0,4).

If you set y = 0, then x = - 20, and the x-intercept is (-20,0).

Plot these 2 pts and then draw a str. line thru them. Done!

If you wish to solve 5y-x=20 for y:

1) add x to both sides: 5y = 20

2) divide both sides by 5: y = 4
