Question

How do I write out a function rule from a table? Can somebody explain in detail, I am very confused.

Answer 1

Answer:

First we need to set up a table, i'll make up some numbers.

y= 2,4,6,8

x=4,8,16,20

x is always over y.

the y values go up 2 each time, and the x values go up 4 each time.

so your format would be y=mx+b

your answer from my example would be y=2x+4.

also i forgot about the $\frac{x}{y}$  your answer for that would be the number it counts up or down by each time, and our answer for this would be $\frac{4}{2}$

I hope this helps!
