A1 - Unit 8 Test - Writing Linear Equations

What does 'b" represent in y=mx+b

• y-intercept

• banana

• x-intercept

• slope

Which statement best describes "m" in the y=mx+b equation?

• x- intercept
• y - intercept
• slope
• matching

What is the y-intercept shown on the graph?

• (0, -2)

• (-2, 0)
• (0, 3)
• (3, 0)

What is the equation of the line?

• The slope is -2, the equation should be
  y = -2x + 5
• The y-intercept is 4, the equation should be

  y = -2x + 4

• The y-intercept is -5, the equation should be y = -2x - 5

Calculate the slope of the line that passes through the

points (1, -8) and (-3, 0).

• 4

• -1

• -2

• 6

In slope-intercept form, write the equation of the line passing through the points (-3,4) and (-4,2).

• y = -2x + 10

• y = -2x - 10

• y = 2x - 10

• y = 2x + 10

What is the equation of the line that goes through the points (2, 9) and (3, 1) ?

• y= 8x - 5

• y= -8x + 25
