Find the solution to the system using a calculator.

y = 3x - 8

y = 4 - x

• (3,1)

• (1,3)

• (-3,1)

• (3,-1)

Solve the system using your calculator.

y = 2x + 1

y = 4x - 1

• (1,3)

• (-1,-3)

• (-1,3)

• (3,1)

Solve for y:

2x + 2y = 6

• y = - x + 3

• y = x + 3

• y = 2x +6

• y = - 2x + 6

Solve for y:

5x - y = 6

• y= 5x - 6

• Y= -5x + 6

• Y= 5x + 6

• Y = -5x - 6

Solve the system using substitution:

y = 4x+1

3x + 2y = 13

• (1, 5)

• (5, 1)

• (-2, 4)

• (3, -3)

Solve the system using substitution:

x = 7 - 2y

2x + y = 5

• (-1,4)

• (4,-1)

• (1,3)

• (3,1)
