y = 2x + 9

x = -3

• (-3, -33)

• (-3, 8)

• (-3, 3)

• (3, -3)

y = 2x - 4

7x - 2y = 5

• (-1, -6)

• (-1, -8)

• (-2, 6)

• (1, -8),

Solve:
y=8x+1
y=6x+3

• (1, 9)
• (4, 14)
• (0, 1)
• (2, 4)

Find the solution of the system of equations below using the substitution method:

y = 2x - 4

7x - 2y = 5

• (-1, -6)

• (-1, -8)

• (-2, 6)

• (1, -8),

y = -2x + 5
y = 2x - 11

• No Solution
• (0, 0)
• (3, -1)
• (4, -3)

Solve the system by substitution.
 
5x + 4y= −14
y =  −7x  −  15
