Answer:
um
Step-by-step explanation:
what problem is their to figure out
Use FOIL
28x² -8xy +7xy -2y²
28x² -xy -2y²
10y - 5x = 40 Add 5x to both sides
10y = 5x + 40 Divide both sides by 10
y =

x + 4
The
y-intercept is 4 and the
slope of the line is 
.
You can find these by comparing your equation to the equation y = mx + b, where m is the slope of the line and b is the y-intercept.
