Using Slope-intercept Form to Graph an Equation
Using the slope-intercept form, the line can be graphed simply by plotting the y-intercept and using that slope to find the second point.

A System with No Solution and a System with Infinite Solutions
Presented is a system of equations to which there is no solution the lines are parallel and a system of equations to which the solution is coincident lines the two equations share the same, infinite number of solutions.

Transcript: SLOPE OF 2, BUT THEY HAVE DIFFERENT Y-INTERCEPTS. THAT MEANS THE LINES FOR THE EQUATIONS MUST BE PARALLEL. PARALLEL LINES HAVE NO POINTS IN COMMON. THERE
