Steps:
1. 5x-2y= 8
2. Subtract 5x on both sides
-2y= -5x + 8
3. Divide everything by -2
Y= 5/2x + -4
4. Now that you have the slope-intercept form, you can graph it.
5. Plot the point -4 on the y-axis
6. Go up 5 and right 2 to get to your next point. Keep on doing that until you run out of room
7. Now do the opposite and start from -4. Now you will go down 5 and left 2 to find each point. That's how you will make your line.
