Question 76697: Graph
y=-1/3x+1
y=1/3x+1

You can put this solution on YOUR website! Graph
y=-1/3x+1
Let x=0 and solve for y
y=-1/3(0)+1
y=0+1
y=1 Plot (0,1)
Let x=3 and solve for y
y=-1/3(3)+1
y=-1+1
y=0 Plot (3,0)
Connect the points and you have
y=1/3x+1
Let x=0 and solve for y
y=(1/3)(0)+1
y=0+1
y=1 Plot (0,1)
Let x=-3 and solve for y
y=1/3(-3)+1
y=-1+1
y=0 Plot (-3,0)
Connect the points and you have
:
Both of these lines are in slope intercept form:  , m=slope and (0,b)=y-intercept.
Their slopes have opposite signs, but the same y-intercept (0,1). If you were supposed of graph these two points together, you would find that they intersect at (0,1). If this is a system, then that's the solution to the system of equations.
Happy Calculating!!!!
