11/8 Homework Quiz 3.4 to 4.1

What is the slope of the line in the graph in the picture?

• -3

• 2

What is the slope of the line represented in the table?

• 0

• Undefined

• -2

What line best states the error made in the picture?

• The y-intercept is undefined, not 0.

• The slope is actually +4

• The y-intercept is -4 and the slope is 0

• This is not slope-intercept form, as the x and y variables need to be switched.

  Write the equation of the line with a slope of 2 and a Y-intercept of 9

Write the equation of the line in the graph pictured in slope-intercept form. If you have an improper fraction, leave it in that form. Example, 7/2

• f(x) = -5x - 4

• f(x) = 4x - 5

• f(x) = 6x - 4

• f(x) = -4x + 6

Find the x and y intercepts of the graph with the linear equation  -3x + 5y = -30

• x-int = (-10, 0)

  y - int = (0, 6)

• x-int = (10, 0)

  y - int = (0, -6)

• x-int = (0, -10)

  y - int = (6, 0)

• x-int = (0, 10)

  y - int = (-6, 0)

Use the x and y intercepts to graph the linear function -12x + 3y = 24
