Equation for this slope

y=x-3 (assuming your graph is counting by ones)

Step-by-step explanation:

Slope is 1, I chose two points.

0,-3  and 4,1

Then found the slope with those two points, which was 1.

Then I find the y-intercept, which is where the line and point crosses the y axis, which was -3.

So, I made my equation.

ou would have 12 of each
