Find the slope of the line that goes through (0,2) and (4,-2)

Start with the slope formula.

y2 - y1/x2 - x1

We take the second y minus the first y
over the second x minus the first x.

So we have -2 - 2/4 - 0.

Simplifying from here, we have -4/4.

This reduces to -1.

So the slope of the line is -1.

If jon had $4.00 then takes away $2.25, then he should have $1.75 left. $4.00 - $2.25 = $1.75 hope this ; )
