Math System of Equations

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

• Parallel lines

• Identical lines 

• Intersecting lines

Solve the system of equations.
y = 4x+1
3x + 2y = 13

• (1, 5)

• (5, 1)

• (0.25, 2)

• ∅

Solve:
3x + 7 = -8

• 5

• -5

• -12

• -18

Solve:
7x - 3x - 8 = 24

• 8

• -8

• 3.2

• 4

What is the solution to this system?

• (1, -1)

• (-1, 1)

• (0, -2)

• (2, 0)

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. 

Which is the graph of y=-x+2?

• A

• B

• C

• D

Solve:
7x + 19 = -2x + 55

• 4

• 14.8

• 8.2

• -4

What is the solution?

• (6, 3)

• (3, 6)

• (-6, 3)

• No solution

The solution to this system is:

• No solution

• (0, 1)

• (0, -2)

• (4, 3)
