You can put this solution on YOUR website! Can you write this equation in function form so I can graph it?
15x + y = 20
:
Subtract 15x from both sides and you have:
y = 20 - 15x
:
Since it's linear you only have to plot a couple points, but a third point will
ensure that you are doing it correctly
Choose values for x: -1, +2, +3, find y and plot them
:
x | y
------
-1 | 35
0 | 20
+1 | 5
+2 |-10
:
It should look like this:
