Unit 6 Mix Practice 1

Lesly graphed two lines in order to find the solution to a given system of equations.
What is the solution?

• (-3,-8)
• (-8,-3)
• (3,-8)
• (8,3)

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. 

How many solutions will this system have?

• One
• Two
• No Solution
• Infinitely Many Solutions

How many solutions will this system have? 

• No solution
• One Solution
• I Don't Know
• 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

Solve for the following system of linear equations:

• (6, -6)

• (-6, -6)

• (6, -8)

• (-3, -6)

Solve for the following system of linear equations:

• (2, -3)

• (3, 2)

• (-3, -2)

• (-2, -3)

• No solution

• (-3,-3)

• Infinitely many solutions

• (-2,1)

What is the first step in solving a system by Substitution?

• Make sure both equations are in standard form.

• Make sure at least one equation is solved for one variable. Get y = or x =

• Make sure both equations are in slope-intercept form.

• Make sure both equations can be solved.
