Graph the following systems and determine the solution set:
1.)x+y=10
2.)x-y=-4
---
Solve both for "y" and plot 2 points for each equation:
x+y = 10
y = 10-x
If x = 0, y = 10
If x = 10, y = 0
---
Plot (0,10) and (10,0) and draw a line thru them to get:
------------------------
x-y = -4
y = x+4
If x = 0, y = 4
If x = -4, y = 0
---
Plot (0,4) and (-4,0) and draw a line thru them to get:
---
Find the point that lies on both lines: (3,7)
