Question

The equation Y = 25 - 5X suggests that an increase in X by the amount of 8 will cause a decrease in Y by the amount of _______

A. 10 B. 25 C. 40 D. 4

Answer 1

Answer #1

Answer 2

Answer #2

SOLUTION :

y = 25 - 5x = - 5x + 25

So, slope = - 5 . It means , run of x by unit causes fall of y by 5 units.

So, if x increases (runs) by 8 units will result in decrease of y by 8*5 = 40 units.

So, 40 : Option C is the Answer.
