Question 92409: how do i graph
y+=+2x+-+1
and
y+=+-x+%2B2
on the same coordinate plane?
what type of lines are formed?
how do i compare their slopes?

You can put this solution on YOUR website!
y=2x-1 (red line) this line has a slope (m=2)
y=-x+2 (green line) this line has a slope (m=-1)
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+y+=+2x+-1%2C+y+=+-x+%2B2%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, y = 2x -1 and y = -x +2).
INTERSECTING STREIGHT LINES ARE FORMED.
COMPARE THE SLOPES -- ONE IS POSITIVE & THE OTHER IS NEGATIVE.
