Answer:
Step-by-step explanation:
Identify the changes in the y values of the table and the x values on the table.
so for example:
x y
1 -2
3 8
5 18
7 28
In this case the changes in the x values are 2,2,2
And the changes in he y values are 10,10, and 10.
So now you write them as fractions like y changes/ x-changes.
So now it is 10/2, 10/2, and 10/2 all of these simplify to 5.
Therefore you slope is 5.
