Algebra 5.2A

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

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

y = −2
4x − 3y =18

• (3,-2)
• (-2,3)
• (2,-3)
• (3,3)

Solve the system of equations.

y = 4x+1

3x + 2y = 13

• (1, 5)

• (5, 1)

• (0.25, 2)

• No solution

Solve the system of equations:
y=2x
x + y = 9

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

Solve:
x = -3y - 17
2x + 3y = -7

• (1, -20)
• (3, 0)
• (-5, -2)
• (10 , -9)

The first step in solving using the substitution method is __________.

• get x by itself
• get y by itself
• get either variable by itself
• add the equations together

x + 2y = 2
x = -4y + 2

• (-3, 0)
• (0, 2)
• (-3, -2)
• (2, 0)

Solve the system of equations using substitution:
3x - y = -8
x = -2

• (2, 2)
• (-2, -14)
• (-2, 2)
• (2, 14)

Solve each system of equations.
y = 3x - 11  
2x + 3y = 0

• (-2,3)
• (-3,2)
• (3,-2)
• (2,-3)
