They put the demand in order to trick you off on something behind it.


So you might need to to use the suppy part
Price Supply
$20 150
$30 250
$50 450
Then you might want to use the point slope form


y-Supply=m%28x-Price%29

but you need to find the SLOPE and substitute so that it look like
m=%28250-150%29%2F%2830-20%29 or m=%28450-250%29%2F%2850-30%29
and your answer should get m=10


Now you need to plug in the slope, supply and the price so you do this:
y-150=10%28x-20%29 or y-250=10%28x-30%29 or y-450=10%28x-50%29


Then multiply to get:
y-150=10x-200 or y-250=10x-300 or y-450=10x-500


You should get


y=10x-50<= Supply Equation


When you graph the supply equation, you should get
graph%28750%2C+750%2C+-50%2C+50%2C+-50%2C+50%2C+10x-50%29
