Answer:
C
Step-by-step explanation:
Multiply the functions.
If Eric plays piano, then David will sing.
The simplified for is 9n+2
Slope = (-3 - (-15))/(-9 - (-5)) = - 12/4 = -3
We will make 2 into a fraction, 2/1. Then, we will multiply it by 4 to get a common denominator. We have 8/4 now. Subtract 8/4 by 1/4, which will give us 7/4. Turn that into a mixed number.
1 3/4 is our answer!
