Sagot :

The linear function that is modeled by the table is given by:

y = -5x - 3.

What is the complete problem?

The problem is incomplete, and was not found on a search engine, but one idea is to find a linear function that models the data in the table.

What is a linear function?

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.

For this problem, we have that when x increases by 3, y decays by 15, hence the slope is given by:

m = -15/3 = -5.

Hence:

y = -5x + b.

When x = 1, y = -8, hence we use it to find b as follows:

-8 = -5(1) + b

b = -3.

Hence the function is:

y = -5x - 3.
