4x = 0

Divide both sides by 4:

x = 0/4 = 0.

This is the line x = 0, or the y-axis. All vertical lines have an undefined slope.

5y = 0

Divide both sides by 5:

y = 0/5 = 0.

This is the line y = 0, or the x-axis. All horizontal lines have slope zero.

I hope that helps. :)

The only line where 4x = 0 (x = 0) is always true is the y axis. It's slope is undefined (tan 90°)

Like wise for 5y = 0. y = 0 and that's the x-axis, which has slope zero (tan 0°).
