I can't plot it for you, but the slope will be the y/x or the rise/run.
You can find the slope by using 2 points of the line and subtracting the (y1-y2)/(x2-x1)
Mr Dupee: $29.99x(1-20%)
=$29.99x0.8
=$24.00
<span>Mr. Edgar: $25x(1-10%)
=$25x0.9
=$22.50
$24.00>$22.50
Mr. Edgar got a better </span>discount.

Step-by-step explanation:
<u>Step 1: Define</u>
11x - 12 = 16 + 12x
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Subtraction Property of Equality] Isolate <em>x</em> terms: -12 = 16 + x
- [Subtraction Property of Equality] Isolate <em>x</em>: -28 = x
- Rewrite: x = -28
