Answer: -3/2</h3>
=================================
Work Shown:
Rise = -3
Run = 2
Slope = rise/run = -3/2 = -1.5
----------------
Notes:
- The rise and run correspond to the vertical and horizontal portions of the triangle shown
- The rise is negative because we're going downhill when moving from left to right, so that also means the slope is negative.
- The run is always positive.
The company A equation is y=21x. The company B equation is y=18x+45
The companies will have the same price after 15 shirts are sold. To show work for this, make x in both equations 15 and you should get 315 as the answer for both. 315 is the amount of money spent on shirts.
