A. y will decrease by 2


B. y will decrease by 1


C. y will increase by 1


D. y will increase by 2

Answer 1

try plugging in x = 2 and x=1 and calculate the 2 values of y

Answer 2

c?

Answer 3

x=2 y = 2(2) - 3 = 1
x = 1 y = 2(2) - 3 = -1

decrease in y = 1 - (-) = 2

A

Answer 4

* 1 - (-1) = 2
