Question

Given the function y = 5x – 7, how does the y-value change as x increases by 1?

A.
The y-value decreases by 7.
B.
The y-value decreases by 2.
C.
The y-value increases by 12.
D.
The y-value increases by 5.

Answer 1

plug the number on x to see how much increases or decreases as follows:

you have now

y = 5x -7 that means (0,7)
y = 5(1)- 7
= 5-7 = -2 (1,-2)
y = 5(2) -7
= 10 -7 (2,3)

Answer 2

so what is happening to y when x increases by 1

Answer 3

I meant the first one should be (0,-7)

Answer 4

im confuse at the max

Answer 5

the range (y) {-7,-2,3......}

what is the sequence

Answer 6

+5 right?

Answer 7

correct

Answer 8

yay!!!!

Answer 9

so D
