ok well the simplified equation would be -y+9 so the coefficient front the variable term would be -1 because there is an implied 1 in front of the variable but it is negative because of the negative sign.
Answer:
-1
Step-by-step explanation:
The only variable term in 6 − y + 3 is y, and the coeff. of y is -1 (first possible answer).
I think answer is
5.X+11
-3x - 5
Average rate of change is just using the slope formula: (y2-y1)/(x2-x1).
1/48
the steps are in the picture
