Old value of 5 devices = 657
New value of 5 devices = 663
Increment cost of 5 devices
663 - 657
6
Therefore the increment for one device
6 / 5
1.2
Answer: - 19/4
Step-by-step explanation:
To find the slope , all we need to do is to write the equation in the form y = mx + c , where m is the slope and c is the y - intercept.
That means we need to make y the subject of the formula in the equation.
4y = 152 - 19x
Divide through by 4
y = 152/4 - 19x/4
y = 38 - 19x/4
Therefore the slope is -19/4
