Question

A table of values of a linear function is shown below. Find the output when the input is n . Type your answer in the space provided.

input: 1 2 3 4 n
output: -10 -13 -16 -19 (Blank)

Answer 1

5; -22

Explanation:

Hope this will help

Answer 2

5; -22

Explanation:

A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional.

Given the following data;

Input: 1 2 3 4 n

Output: -10 -13 -16 -19

For an input variable of 1, 2, 3, 4; the output variable is -10, -13, -16, -19 respectively.

To find the value of n;

We can deduce that the input is increasing by a value of 1.

Thus, n = 4 + 1 = 5

For the output;

We can deduce that the output is increasing by a value of -3.

Thus, the next output = -19 + (-3) = -22
