Systems Summative Review

How many solutions does the system of equations have that is graphed here?

• One

• Two

• None

• Infinite

How many solutions does the system of equations have that is graphed here?

• One

• Two

• None

• Infinite

What is the solution to the system of equations that is represented in the graph?

• (3, 2)

• (-2, 3)

• (3, -2)

• Infinite

Is the points (-4, 4) a solution to the system of equations?

• Yes

• No

Is the point (2, -1) a solution to the systems of equations below?

y=5x+3

y=-2x-4

• Yes

• No

What is the solution to the system?

• (-1, 3)

• (-3, 1)

• (3, -1)

• (-3, -1)

Find the slope and y - intercept

y = 1/2x - 1

• slope: 1/2 y-intercept: -1

• slope: 2 y-intercept: -1

• slope: 1/2x y-intercept: 1

• slope: 2 y-intercept: 5

Why will this system have infinite solutions?

• The equations are both negative.

• The equations are the same.

• They have the same y-intercept but not the same slope.

• They have the same slope but not the same y-intercept.

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

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

If two equations have the SAME SLOPE AND SAME Y-INTERCEPT...

• they will have one solution

• they will have no solution

• they are the same line - they will have infinitely many solutions
