Question:

Kayden creates a linear function where x is the input, y is the output, and m and b are constants.

A. Which equation could represent Kayden's function?

B. Which statement about the graph of Kayden's function is true for all values of m and b?

Answer Options:

A. 

  • begin mathsize 12px style y space equals space 1 over x space plus m b end style
  • y = mx + b
  • x = my • by

B. 

  • The graph is increasing
  • The graph is decreasing
  • The graph goes through the origin
  • The graph has a constant rate of change

Code Description
MAFS.8.F.1.3: Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear. For example, the function A = s² giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.
