Okay, I'm not sure if I'm understanding this right but I think the equation to find the sale price would be x-30%.

The regular price of $8.96 should be 11.65.

Good strategy for using slope formula

Fantom [35]

I personally use y2-y1 over x2-x1 because it's simple. Plot two y values and two x values. The first ones you plotted are x1 and y1, the others are x2 y2. Now subtract y2-y1 and x2-x1. Afterwards, divide the y value by the x value, that will give you slope.
