What is the slope-intercept form of a line?

• Ax + By = C

• y = mx + b

• y - y1 = m(x - x1)

• y = Ax + By

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

Which of the following equations is written in STANDARD form?

• y=3x-5
• 3x+16=5y
• 2/3 x + 9/13 y = 21
• 5x+7y=-12

Write the standard form of the equation for the line:

y = 1/4 x + 4

• x + 4y = 8

• x - 4y = -16

• y = x + 16

• 4y + x = 8

Jamila went to the sale at Kohl's last weekend.   T-shirts (x) were on sale for $15 each and hoodies (y) were on sale for $20 each.  She spent $150 total. Which equation correctly models this situation?

• 20x + 15 = y 
• 35x = y 
• 15x + 20y = 150 
• 150 - 20x = 15y
