Standard form of a Linear Equation

What is standard form of a line?

• y = mx + b

• Ax + By = C

• y - y1 = m(x - x1)

• y = Ax + By

Which equation is written in STANDARD form?

• y = 1/2x + 2
• y - 3 = -5(x + 2)
• 7x + 2y = 9

• 3x + 2 = y

Put this into standard form:

y = 3x + 2

• y + 3x = 2

• 3x + y = 2

• 3x - y = -2

• 3x - 2y = 2

Put this into standard form:

3x = 7y - 5

• 3x - 7y = -5

• 3x - 7y = 5

• 3x + 7y = 5

• 3x + 7y = -5

Put this into standard form:

14x + 23 = -5y

• 14x + 5y = 23

• 14x - 5y = 23

• 14x + 5y = -23

• 14x - 5y = -23

Solve for y: 
8x + 4y= 16

• y = -8x + 16
• y = 2x -4
• y = -2x + 4
• y = -8x + 12

Student tickets for Oklahoma! cost $5, and adult tickets cost $10. On Friday night, the drama department made $850. What equation would model this?

• 5x + 10y = 850

• 5x - 10y = 850

• x + y = 850

• 850y = 5x + 10
