Answer:
Y1 intercept = 2
(0,2) (3,-7)
m= (-7 - 2) / (3-0) =-9/3 = - 3
Then y = - 3x + 2
Y2 intercept = - 8
(0,-8) (3,-7)
m = (-7 - - 8) / (3-0) = 1/3
Then y= (1/3)x-8
-15xsquared+7x+2 is the answer
Step-by-step explanation:
First you would divide $2.09 by 12 and you would get 0.17 as the answer then you would multiple 0.17 times 18 and you get the answer of $3.06
