SOLUTION: sketch the graph of the equation 5x+4y=20

Question 279074: sketch the graph of the equation 5x+4y=20
Answer by oberobic(2304) (Show Source): You can put this solution on YOUR website!
First, get it in y = mx+b format so that you can graph it.
5x + 4y = 20
subtract 5x from both sides
4y = -5x + 20
divide both sides by 4
y = -5/4x + 5
.
x = 0, y = 5 results in the point (0,5)
x = 4, y = 0 results in the point (4,0)
.
with two points you can graph a straight line
.
