  • Question 1
    60 seconds
    Q. Given that the slope is  -4 and the y intercept is -4 what is the equation of the line?
    answer choices
    y = 4x - 4
    y = -4x - 4
    y = -4
    y = -4x + 4
  • Question 2
    45 seconds
    Q. Identify the slope and y intercept in the equation of the line: y = -1/3x + 1
    answer choices
    Slope: 1/3
    y-intercept: 1
    Slope: 1/3
    y-intercept: -1
    Slope: -1/3
    y-intercept: 1
    Slope: -1/3
    y-intercept: 0
  • Question 3
    30 seconds
    Q.  Identify the slope-intercept equation:
    answer choices
    y = 2x - 2
    y = -2x + 2
    y = -2x + 4
    y = 2x + 4
  • Question 4
    60 seconds
    Q. What is the slope intercept form of the equation
    -8x+2y=4
    answer choices
    y= 1/2 + 8x -4
    y= 2 - 4x
    y= 4x + 2
    y= 4x - 8y
  • Question 5
    300 seconds
    Q. Change the following to slope-intercept form:
    5x - 5y = 25
    REALLY Write this on your paper and work it out!
    answer choices
    y = x - 5
    y = 5x - 1
    y = -x + 5
    y = 5x + 1
