Question

Explain why the equation is not linear.

5/x - y = 1

A. x Should be an exponent.

B. The x variable appears in the denominator.

C. The coefficient of both variables must be equal.

D. There should be an exponent of 2 on either x or y.​

Answer 1

Answer:

B. The x variable appears in the denominator.

Step-by-step explanation:

Given

$\frac{5}{x} - y = 1$

Required

What makes it not linear

First, make y the subject

$y = \frac{5}{x}+1$

A linear equation is represented as:

$y = mx + b$

Notice that the exponent of x in the general form is: 1

This means that x has to appear as a numerator

In $y = \frac{5}{x}+1$, the exponent of x is -1

This means that x has to appear as a denominator

Hence, (b) is true
