Find 2 coordinates on the graph : (0, -20) and (10, 10)

Slope = (10 - (-20) ) / (10 - 0) = 30/10 = 3

Slope = 3

y-intercept = (0, - 20)

Equation : y = 3x - 20

Since the right hand side is shaded,  the equation is y > 3x - 20.

Graph the system of equations on graph paper.
MrRa [10]
Ths system of equations is

<span>8x+6y=48 ..............>y = 48/6 -8x/6
2x−3y=−6 ..............>y = 6/3 + 2x/3

If we use a graphic tool, we can easily check the solution, 
which is (x,y) = (3,4)

The ordered pair lies in Quadrant I
