SOLVING SYSTEMS OF EQUATIONS BY GRAPHING

How many solutions?

• One Solution
• No solution
• Infinitely Many Solutions

If a system of equations has no solution, what does the graph look like? 

• intersecting lines
• parallel lines
• skew lines
• intersecting lines

When you graph the exact same equation twice,

• you will have no solution. 
• you will have one solution.
• you will have infinite solutions. 
• you will graph a giraffe. 

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. 

These two lines intersect at _____.

• (4, -2)
• (4, 2)
• (-2, 4) 
• No solution

The solution to this system of equations is:

• (4, 3)
• (3, 4)
• (-4, 3)
• No solution
