Now you divide forty by five since that is what you did to 15 to get three.
40÷5= 8
The 40 oz and $8.00 i think
Answer =-0.7x +0
Find the gradient by y2-y1/x2-x1
-14 -7/ 20- -10
-21/30
-0.7
And plug in the coordinates to find the y intercept
7= -0.7 (-10) + c
C=0
C would be your answer and here is how you would solve the problem.
