Y= -1/2x -1
first use the formula y2-y1/ x2-x1
then plug in (-10, 4) and (-16, 7) into the formula so it should look like 7-4/ -16 +10
that should simplify down to -1/2
Next plug one of the points into the new formula y=-1/2x +b to find B
Answer:
Right now I'm wondering what kind of class you are taking to get such a weird graph, but I graphed it for you on the screenie.
Step-by-step explanation:
You should though recheck your question for exponents, as 9x2 could be interpreted differently.
Since exponents to not transition well here, I can assume that it was a 9x^2, so please add an exponent symbol ^ between the variables and exponents next time.
268 / 28 = 9.57
9.57 x 21 = 201
Therefore, the answer is 201.
