Systems of Equations Review

A system of linear equations is... 

• Math Magic
• One Equation
• Always more than 2 equations
• A set of 2 or more equations

What is the solution to the system?

• (0, 3)
• (1, -1)
• (-3, 1)
• (1, 3)

What is the solution?

• (2, 2)
• (3, 2)
• (3, 4)
• (2, 3)

Solve for x and y
y = 2x + 1
y = 4x - 1

• (1,3)
• (-1,-3)
• (-1,3)
• (3,1)

y = x - 2
-2x + 3y = -1

• (5, -3)
• (5, 3)
• (-5, -3)
• (-5, 3)

x - 3y = -13
4x + 2y = 4

• (1, 4)
• (-1, -4)
• (-1, 4)
• (1, -4)

What is the solution to the system?

• (3, -1)

• (2, -6)

• No Solution

• (6, -2)

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
• -2
• (1, 2)
• (1, -2)

• A
