Is a proportional function f(x) = 5x linear? Why or why not? Explain with an example.

RideAnS [48]

Given two variables x and y, y is directly proportional to x (x and y vary directly, or x and y are in direct variation) if there is a non-zero constant k such that

y = kx,

The relation is often denoted, using the ∝ symbol, as

y ∝ x

in this case k = 5/1

The percentage error is 11.1%

<h3>What is percentage error?</h3>

Percentage error is simply the difference between the exact and the estimated values as a percentage

The given parameters are:

Estimate = 45
Actual = 50

The percentage error is then calculated as:

$\% E = \frac{50 - 45}{45} \times 100\%$

Evaluate the difference

$\% E = \frac{5}{45} \times 100\%$

So, we have:

$\% E = \frac{500}{45} \%$

$\% E = 11.1\%$

Hence, the percentage error is 11.1%
