Question

Use the table to write a linear function that relates y to x
(table is below)

Answer 1

Use the slope formula of y=mx+b
then use 2 ordered pairs to use in our equation. Label them as (X1, Y1) and (X2, Y2)
Then plug them into this:

\[m=\frac{ Y2-y1 }{ X2-x1 }\]

This gives us our "x" variable.
Now, for our "b" term aka the y-intercept. we were blessed enough to be given that in the table. This can be found when we have (0, y). So, in other words we need to see when x=0, what is the y-value? In this situation we were given (0,0) so we know our "b" is going to be 0.

Make sense? Any further questions please feel free to ask, and best of luck (:
