5. The graph shows the function f(x) =-1/4x+2 3/4 and
g(x) = 1/2x + 1. What are the solutions to the equation
- 1/4x + 2 3/4 = 1/2x + 1?

First, change the mixed number into an improper fraction : 1 3/4 = 7/4
Then, write -7 as an improper fraction. You now have this expression:

-7/1 x 7/4.

Multiply each numerator and denominator, and you get your -49/4, which reduces to -12 and 1/4, or -12.25
