120+10+5=135
I don't know if all you're supposed to do is add or not... so i may be wrong....
We have been given a table that shows a linear relationship between x and y. We are asked to find the rate of change change of y with respect to x.
To solve our given problem, we will find the slope of the line passing through the given points.

Let us find slope of line using points
and
.




Therefore, the rate of change of y with respect to x is
.
10 because there is 4 zero's behind the one. Hopes this helps!! :)
