Question

Find the equation of the linear function represented by the table below in slope-intercept form.

x y
1 1
2 -2
3 -5
4 -8

Answer 1

Slope intercept form is Mx+b

So let’s find a pattern
I see that you are subtracting by 3
So y=-3x+

Now to find b you need to take a step back so add 3
B is 4

Y=-3x+4

Now always check your work

-3(2)+4
Which equals -2

So your equations is y=-3x+4
