What has a steeper line y=2x-3 or x-5y=20

Y=2x-3 has a steeper line because the bigger the slope, the more it goes up on the y-axis for every one spot on the x-axis. 
The first one goes up 2 spaces for every one it goes over, and the second one goes up one space for every 5 it goes over

X - 5y = 20
-x -x

-5y = -x + 20
/-5 /-5 /-5

y = 1/5x - 4

y = 2x -3 is steeper because the slope is increasing faster than the slope of y = 1/5x -4
