Question 205890: By looking at two linear equations, how can you tell that the corresponding lines are parallel?
How do you interpret the solution of a system of equations by the corresponding graph?

You can put this solution on YOUR website!
A)Change both equations to the slope intercept form.
The slope should be equal in both equations.
B)The solution should be the point at which the two lines intersect on the graph.
You may have two equations that don't intersect, then you have no solution for the system.
