Answer:
A) y will increase by 4 unit.
B) y will decrease by 20 units
Step-by-step explanation:
Given equation that shows relation between x and y.

A) If x is increased by 4 units
New value of y = 


So, change in y = new value of y- original value of y



Thus, the value of y will be increased by 4 units.
B) If x is decreased by 5 units
New value of y = 


So, change in y = new value of y- original value of y



= -20
Thus, the value of y will be decreased by 20 units.
