The formula is y=mx + b, or rearranged would be m= y/x -b/x.
The discriminant of the equation
is 76.
I hope that helps.

Step-by-step explanation:
This question sets up the equation tan20°=x/2,500. Solve for X by multiplying 2,500 on both sides giving you x = 2,500tan20°. Finally, plug that in a calculator and you get 909.92. Round it to the nearest foot and you get 910
-36x+30
-24x+20
-18x+15
