Solving Systems Quiz

What is the solution to the system of equations?

• (1, -1)

• (-1, 1)

• (0, -2)

• (2, 0)

What point satisfies the system of equations?

• (2, 2)

• (3, 2)

• (3, 4)

• (2, 3)

The equations of two lines are:

2x - y = 4 and y = -2x + 8.

What is the value of x in the solution for this system?

• x = 8

• x = 3

• x = 11

• x = 5

What is the solution to the system of equations?

x - y = 11

2x + y = 19

• (10,-1)

• (-1,10)

• (3,-4)

• (6,7)

Which response correctly shows the first step of substitution?

y = 2x - 11

-3y = -6x - 15

• -3 (2x - 11) = -6x - 15

• -3y = 2x - 11

• -3y = -6 (2x - 11) - 15

• This problem cannot be solved using substitution.

If a system of equations has infinitely many solutions, what does the graph look like? 

• intersecting lines
• parallel lines
• skew lines
• the same line (coinciding lines)

What is the solution to the system of equations?

• No solution

• (0, 2)

• (0, -4)

• (3, -3)

Which point satisfies the system of equations shown in the table?

• (-1, -1)

• (0, 2)

• (1, 5)

• (3, 11)

Which of the responses shows the first step of substitution?

y = 2x + 1

3x + y = 16

• 3x = 2x + 1

• 16 = 2x + 1

• 3x + y = 2x + 1

• 3x + (2x + 1) = 16
