Answer:
A is the answer
Step-by-step explanation:
What you do is you cross multiply 24x4 which equals 96. Then, you divide by 16. Which gives us: m = 6
The formula is y-y0=m(x-x0)
So we plug in the Y's and the X's given:
-5-9=m(0-(-3)) >>>> -14=m(3)>>>>> m=-14/3
The next formula is y=mx+b , choose any point to use for X and Y: I'm gonna choose (0,-5)
-5=-14/3(0)+b >>> b=-5
Your formula is: y=-14/3x-5
21+21= 42 cookies minus 4 = 38 cookies
38/3= 12.66(round down to 12)
