Solving System of Equations

Buzz graphed two lines in order to find the solution to a given system of equations.
What is the solution?

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

^{What is the solution?} 

• 1
• -2
• (1, 2)
• (1, -1)

Solve the system of equations.

y = x +6

y = 4x

• (2, 8)

• (-2, -8)

• (6/5, 2)

• (-6/5, -2)

Solve for x and y.

y = 2x - 7

y = x

• (-7, -7)

• (0, 0)

• (7, 7)

• (-3,0)
