Tell whether the ordered pair is a solution of the equation.

y = 4x; (0,4)

• yes

• no

Tell whether the ordered pair is a solution of the equation. y = 3x; (2, 6)

• yes

• no

Tell whether the ordered pair is a solution of the equation.

y = 5x - 10; (3,5)

• yes

• no

Tell whether the ordered pair is a solution of the equation.

y = x + 7; (1,6)

• yes

• no

Identify the steps to solve for b

• Add 6 to both sides

  Then divide both sides by 5

• Add 6 to both sides

  Then multiply both sides by 5

• Subtract 6 from both sides

  Then multiply both sides by 5

• Divide both sides by 5

  Then add 6 to both sides

• Multiply both sides by 6

  Then add 5 to both sides

Choose the equation that represents the following situation:

You bought a $5 magazine and four books. You spent a total of $25. How much did each book cost?

• 5 + x + 4 =25

• 5 + 4x = 25

• 5x = 25

• 25 + 5 = x

• 25x + 5 = 125
