QUESTION: SOLVE THE SYSTEM BY GRAPHING
E1) X-Y=5
E2) X+Y=3
:
Graph E1)
Let x=0 and solve for y:
0-y=5
-y=5
-(-y)=-(5)
y=-5
Plot: (0,-5)
Let y=0 and solve for x:
x-(0)=5
x=5
Plot: (5,0)
Connect the dots and you have this line:

Gaph E2)
Let x=0 and solve for y:
(0)+y=3
y=3
Plot (0,3)
Let y=0 and solve for x:
x+(0)=3
x=3
Plot (3,0)
Connect the dots and you have a second line:

Their point of intersection is the solution: (4,-1)
Happy Calculating!!!
