The answer is 3/2
Find the slope of the line
M = y2-y1/ x2-x1
M=9-0 /6-0
M=9 divide 3 / 6 divide by 3
M= 3/2 cm/s
For this case we have to:
x: It is the variable that represents the number of compact discs.
The cost function must be found considering that each disk costs $7.13. So:

Thus, to find the total cost of "x" compact discs (in $) we substitute the number of discs in the cost function.
Answer:

Dude it keeps saying incorrect when i put the answer bro it says it again
Answer:
x = (-5+9)/2 = 2
y = (-7+ (-8)) /2 = (-15)/2 = -7.5
