solve the system of equation 2x + 5y = 20, y = x - 3 by graphing
2x + 5y > 20, y < x – 3 by graphing

Hi

solve the system of equation  by graphing 

2x + 5y = 20   Pt(0,4) and Pt(10,0) on this Line  Blue

y = x - 3      Pt(0,-3) and Pt(3,0) on this Line  Green

Plot points for each line and connect these with the corresponding lines.



As to: 2x + 5y > 20  and  y < x – 3 

Now You may 'shade' the area above the blue 'in the area' BELOW the green 

to show the graphical solution to this system of Inequalities

Cannot demonstrate here..it would be that area between the lines on right side
