Solving Systems of Linear Equations

Does the system have one, none or infinite solutions?
8x + 4y = 12
y = -2x + 3

• (0,3)

• (3,0)

• No solution(parallel lines)

• Infinitely many solutions

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

• (1,3)

• (-1,-3)

• (-1,3)

• (3,1)

What is a solution of a linear system if the lines are the same?

• One solution

• No solution

• Infinitely Many solutions

Solve the system of equations.
x + 2y = -3
x - y = -12

• (-9, 3)

• (-7 ,5)

• (3, 15)

• (9, 6)

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?

• One Solution

• No solution

• Infinitely Many Solutions

What is a solution of a linear system?

• the slope of the line

• the y-intercept

• the point where the systems intersect

• the rise over tun

What is the solution of a linear system that has parallel lines?

• One solution

• No solution

• Infinitely Many solutions

• A
• B
• C
• D

Solve:
-2x + 5y = -1
4x - 2y = -6

• (-2, -1)

• (2, 7)

• (3, 1)

• (-1, -2)
