Someone slope please ?

The slope is -4/7

You can visually count how many lines you go up and over from one to the other.

But another way to figure this out is the slope formula :

y2-y1 / x2-x1

The points as seen in the graph are (-4,3) and (3,-1)

Plus those values into the formula.

-1 - 3 / 3 - (-4)

-4/7

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 ; )
