How can you use a table to write an equation?

You can use a table to write linear equations.

For example, lets have a table:

x    y

4    36

6   56

9   86

In the x table, we can see that 4 and 6 are 2 numbers apart, and 6 and 9 are 3 numbers apart.

In the y table we can see that 36 and 56 are 20 numbers apart, and 56 and 86 are 30 numbers apart.

In this example, we can write a slope. y = mx + b

Tables are helpful because they show you evidence on where you can plot your graphs with y = mx + b

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

thats not a system of equations, that is a solution
