If a system of linear equations has one solution, what does this mean about the two lines? 

• Parallel lines
• the same line 
• Intersecting lines

Parallel Lines never intersect because...

• they have the same slopes. 
• they have the same y-intercept.
• they have different slopes.
• they have different y-intercepts.

How do you graph the equation
y=-3x +15?

• Plot the point (15,0). Then go down 3 right 1 to plot the next point.
• Plot the point (0,15). Then go down 3 right 1 to plot the next point.
• Plot the point (0,15). Then go down 3 left 1 to plot the next point.
• Plot the point (15,0). Then go down 1 right 3 to plot the next point.
