  • f(x) = -2/3x - 11
  • f(x) = -1/2x + 1
A line that passes through the points (-4, 10) and (-1, 5) can be represented by the equation y = (x - 2). Which equations also represent this line? Check all that apply.
  • y - 12 = -5(x + 2)
  • y = x/3
  • y = -5/3x + 10/33y = -5x + 105x + 3y = 10
  • m = 20 because the rate of change is -3.

Which linear function is represented by the graph?
  • f(x) = -1/2x + 1
  • y = 1/4x - 2
  • f(x) = 1/2 x + 6

  • 5
  • -9
At a glance, Kendra believes that the function represented on the graph is linear.How can Kendra determine if the function is actually linear?
  • She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.
  • y + 6 = 5/2 (x + 2)
  • The line does not represent a direct variation because it does not go through the origin
  • The line of g(x) is steeper and has a lower y-intercept. (This answer has been noted as mostly wrong.) so, don't trust this one.
Line MN passes through points M(4, 3) and N(7, 12). If the equation of the line is written in slope-intercept form, y = mx + b, what is the value of b?
  • 6
  • -2/5
  • -9
  • -4
A direct variation function contains the points (-9, -3) and (-12, -4). Which equation represents the function?
  • f(x) = -2/3x - 11
  • y - 1 = 3x
  • f(x) = 1/2x + 6
  • y = x/3
The table represents a linear equation.Which equation correctly uses point (-2, -6) to write the equation of this line in point-slope form?
  • y + 6 = 5/2 (x + 2)
  • y - 12 = -5(x + 2)
  • x y1 32 73 11 4 15
  • f(x) = 1/2 x + 6
How does the slope of g(x) compare to the slope of f(x)?
  • y = -5/3x + 10/33y = -5x + 105x + 3y = 10
  • The slope of g(x) is less than the slope of f(x).
  • The line does not represent a direct variation because it does not go through the origin
  • The line of g(x) is steeper and has a lower y-intercept. (This answer has been noted as mostly wrong.) so, don't trust this one.
A line is drawn through (-4, 3) and (4, 3). Which describes whether or not the line represents a direct variation?
  • The line does not represent a direct variation because it does not go through the origin
  • The slope of g(x) is less than the slope of f(x).
  • y = -5/3x + 10/33y = -5x + 105x + 3y = 10
  • The line of g(x) is steeper and has a lower y-intercept. (This answer has been noted as mostly wrong.) so, don't trust this one.
Mr. Shaw graphs the function f(x) = -5x + 2 for his class. The line contains the point (-2, 12). What is the point-slope form of the equation of the line he graphed?
  • y + 6 = 5/2 (x + 2)
  • y = -5/3x + 10/33y = -5x + 105x + 3y = 10
  • y - 12 = -5(x + 2)
  • y - 1 = 3x
