A television game show begins with 20 contestants. Each week, the players vote 2 contestants off the show. What is the rate of c
nadya68 [22]

Using a linear function, it is found that the rate of change in this problem situation is of -2 contestants per week.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Considering the situation described, the number of participants after n weeks is given by:

N(n) = 20 - 2n.

The slope is of -2, hence the rate of change in this problem situation is of -2 contestants per week.
