Linear and Systems of Equations Review

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

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

What is the solution?

• (1, -1)
• (-1, 1)
• (0, -2)
• (0, 1)

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

• Parallel lines
• the same line 
• Intersecting lines

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

• (1, 5)
• (5, 1)
• (0.25, 2)
• ∅

Determine if (4, 1) is a solution for the system of equations. You may use Desmos to determine your answer.
y = -x + 5
y = 2x - 7

• yes
• no

How many solutions?

• One Solution
• No solution
• Infinitely Many Solutions

What is the solution?

• (6, 3)
• (3, 6)
• (-6, 3)
• No solution

^{What is the solution?} 

• 1
• -2
• (1, 2)
• (1, -1)

What is the solution to the system?

• (0, 3)
• (1, -1)
• (-3, 1)
• (1, 3)

Solve by graphing in Desmos
y = 2/3x - 2
y = -x + 3

• (0,3)
• (0,-3)
• (3,0)
• (-3,0)
