4x%2B5y=20 Start with the given equation.


5y=20-4x Subtract 4x from both sides.


5y=-4x%2B20 Rearrange the terms.


y=%28-4x%2B20%29%2F%285%29 Divide both sides by 5 to isolate y.


y=%28%28-4%29%2F%285%29%29x%2B%2820%29%2F%285%29 Break up the fraction.


y=-%284%2F5%29x%2B4 Reduce.


So the equation y=-%284%2F5%29x%2B4 is now in slope intercept form y=mx%2Bb where the slope is m=-4%2F5 and the y-intercept is b=4 note: the y-intercept is the point

Find the slope(m) and y-intercept of the line
4x + 5y =20
---
5y = -4x + 20
y = (-4/5)x + 4
--
slope = -4/5
intercept = 4
