Help me please

There are two questions in the picture, but I'll answer them both. Before you go any further, you should be familiar with the process of substitution. Substitution allows you to replace a variable with a known numeric value. I didn't complete the tables entirely, but hopefully the way I explained it will help you finish the problems.

1. y = 1.5x

if x = 1, then y = 1.5(1) = 1.5

if x = 2, then y = 1.5(2) = 3

if x = 3, then y = 1.5(3) = 4.5

See how we simply replace the x with the value of x? To find another solution, simply find a point that is on the line. For example, we could find x = 10.

y = 1.5(10) = 15

Therefore, another solution on the line is (10, 15).

2. y = 1.25x

if x = 1, then y = 1.25(1) = 1.25

if x = 3, then y = 1.25(3) = 3.75

You can use a similiar process as problem #1 to finish.
