Question

The table represents some points on the graph of a linear function.

x −1 −0.5 2 3.5 5
y 6.5 5.25 −1 −4.75 −8.5
Which equation represents the same relationship?


y=2.5x−4

y=−2.5x+4

y=−4x+2.5

y=4x−2.5

Answer 1

The answer is:

y= -2.5x + 4

You have to do -2.5 times the x value

Then add 4 and you should get the correct number for each y value.
