9. The slope for this one is 21 bc y1-y2/x1-x2 is the slope formula and this can be used between any two points (I used the first two) -30-(-54)/ 7-11 which is -84/-4= 21
10. Rate of change is the same thing as slope so 4.5-5/18-20 which is -0.5/-2 which means the rate of change is 2.5
11. 23-39/1-3 which is -16/-2 which means the rate of change is 8
12. 5/4 is 1.25 so the sports drink costs 1.25$ each
Hope this helped :)
The answer is to the qieston would be B

Answer:
C
Step-by-step explanation:
Look at the coefficients in the expression: -3 and 12. The largest number that divides them both is 3. That means you can factor out either a 3 or a negative 3. Try 3.
3(-x - 4) is not on the list of answers. Also, it's unusual to factor out a value that leaves a negative coefficient on x.
Try factoring out -3.
-3(x + 4) is answer choice C.
Bonus
Because this is a multiple-choice question without a "non of these" option, you can solve the problem by expanding--multiplying out--the answers!
A. 3(x + 4) = 3x + 12 ...nope, not it
B. 3(x - 4) = 3x -12 ...nope, not it
C. -3(x + 4) = -3x -12 ...bingo!
