You can put this solution on YOUR website! 2x+y=5
Y=-2X+5 (RED LINE)
3x-y=10
-Y=-3X+10
Y=3X-10 (GREEN LINE)
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions -2x +5 and 3x -10).
(3,-1) SOLUTION TO THESE EQUATIONS.
Answer by rfer(16322) (Show Source):
You can put this solution on YOUR website! change the equation to slope intercept form
y=mx+b
y=-2x+5
m=slope=-2
b= y int=(0,5)
start from b with negative slope -2/1. over 1, down 2
--------------------------
y=3x-10
b= (0,-10)
m=3/1, 1 over, up 3
