Yes, the given relation is a function.

Step-by-step explanation:

As given,

(4, 9)

(5, 7)

(9, 8)

(12, 15)

x                          y

4                          9

5                          7

9                          8

12                         15

As each input has different and unique output values.

So, the given relation is a function.

what does the slope of -1 tell you about thr relationship between lengths and widths of rectangles with perimeter 24?
NeX [460]

Using linear function concepts, the slope of -1 means that when one of the length/width is increased by 1, the other is decreased by 1.

<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.

In this problem:

  • The lengths and the widths are interchangeable, that is, either can be considered as the input or as the output.
  • The slope of -1 means that when the input in increased by 1, the output is decreased by -1, that is, when one of the length/width is increased by 1, the other is decreased by 1.
