Question 838737: graph each pair of lines to find their point of intersection.
a) y=3x+8
x+2y=2
Answer by richwmiller(17219)   (Show Source):
You can put this solution on YOUR website! These are linear equations so you only need two points each.
Choose x=0 and y=0
y=3x+8
x=0
y=8
plot(0,8)
y=0
0=3x+8
3x=-8
x=-8/3 which is almost -3
plot (-8/3,0)
connect those two points
x+2y=2
x=0
y=1
plot (0,1)
y=0
x=2
plot (2,0)
connect those two points
