Linear Equation Forms

If m=3 and b=6, what is the correct slope intercept equation?

• y=3-6

• y=3x-6

• y=3x+6

• y=6x+3

Which equation is being represented by this line?

• y = -1x + 2

• y = 1/2x + 2

• y = 3x -4

• y = -3x +2

The Roaming Cell Phone Company charges $15.00 per month plus $0.20 per minute of airtime usage.  If Juanita uses x minutes of airtime, what is an equation that can be used to determine her monthly cell phone bill (C)?

• C = 0.20x + 15

• C =15 (0.20x)

• C = 15 + x + 0.20

• C = 0.20 + 15x

Would you write a linear equation to model the following situation in slope-intercept form or standard form? 
Mrs. Harris is going to the movies. She spends $10 per ticket and $5 per bucket of popcorn. She only wants to spend $50. 

• Slope-intercept

• Standard form

Easy Car Rental charges $8.50 an hour plus a rental fee of $25.50. Which equation represents the total charges for x hours?

• y = 8.5 + 25.5

• y = 25.5 + 8.5x

• y = 8.5 + 25.5x

A man is climbing down from 100 feet high descending 30 feet per minute.

• y = 100 - 30x

• y = 100 + 30x

• y = 100x + 30

• y = 100x - 30

Solve for y
8x + 2y = -10

• y = -8x + 5

• y = -4x - 5

• y = -¹/₄ x - 10

• y = -¹/₄ x - 5

Rewrite to slope intercept form.
y - 4 = 2(x + 6)

• y = 2x + 10

• y = 2x + 8

• y = 2x + 16

• y = 2x + 20

What is the x and y intercept for the following equation ?
4x - 10y = 20

• x - int = - 4    
  y-int = 10

• x-int = 5
  y-int = 2

• x - int = 5
  y int = -2

• x -int = 4
  y -int = -10

Write the equation in point-slope form for the line that contains the points
(-2, -3), (4, 3)

• y - 3 = 1(x - 2)

• y + 3 = 1(x + 2)

• y -3 = -1(x + 2)

• y + 3 = -1(x - 2)
