Solve:
y= 4x + 9
y = 5x + 10

• (-1, 5)
• (9, 19)
• (-1, -1)
• (9, 1)

Substitute. Which equation is the next step for solving the system of equations?

y = 2x - 2

4x + 3y = 45

• 4x + 3(2x - 2) = 45

• 4x + 3y(2x - 2) = 45

• 4x + (2x - 2) = 45

• (2x - 2) = 45

Find the slope of:
(12,-2) and (4, -6)

• -1/2
• 5/7
• -2
• 1/2
