Question

Which function is the same as the linear

function represented by the table?
x y
-4 -14
-2 -8
0 -2
2 4
4 10

Answer 1

y=3x-2

Explanation:

We know the equation ends in -2 because when x is zero, y is -2

To find the rest of the equation take any other point and take away the -2 from y

Then divide the y by the x to see how may times larger (or smaller) the y is then the x

(I chose -14)

-12÷-4=3

y=3x

the put the -2 back at the end because otherwise, your -14 would be a -12 and that is not a point on the table
