How many solutions will this system have? 

• No solution

• One Solution

• I Don't Know

• Infinitely Many Solutions

How many solutions will this system have?

• One

• Two

• No Solution

• Infinitely Many Solutions

Which statement is true based on the graph?

• At 7 weeks, both Renee and Paul will have saved $80.

• At 8 weeks, both Renee and will have saved $70.

• At 8 weeks, Renee will have saved more than Paul.

• At 9 weeks, Paul will have saved more than Renee.

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. 

Decide if the following statements are true or false about the graph.

Groups:

(a) True

,

(b) False

• The lines are perpendicular which means they will not ever cross.

• The lines will not intersect, so the system has no solution

• The slopes are equal, so the system has infinitely many solutions

• The slope(m) of the lines are equal

• The line are parallel, so the system has no solution

• The lines will eventually touch, so the system has one solution

Which statement describes Kayla's solutions?

• Her solutions are correct.

• She marked the y-intercepts instead of the x-intercepts.

• She marked the y-intercepts instead of the intersection point of the two lines.

• She marked only the y-intercepts instead of the x- and y-intercepts.

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

• Parallel lines

• the same line 

• Intersecting lines

What does the y-intercept represent in this situation?

• The starting cost of fence installation is $150.

• The starting cost of fence installation is $100.

• The starting cost of fence installation is $0.

What is the y-intercept?

• 2

• 12

• 6

• 0

What does the y-intercept mean in this situation?

• The starting price of the pool pass is $0.

• The starting price of the pool pass is $12

• You can buy 6 passes.

• The starting prices of the pool pass is $6.
