Q4. State whether each equation or f... [FREE SOLUTION]

Chapter 2: Q4. (page 65)

State whether each equation or function is linear. Write yes or no. If no, explain your reasoning.
$4 . x^{2} + y^{2} = 4$

Short Answer

Expert verified

No, the equation $x^{2} + y^{2} = 4$ is not a linear equation.

Step by step solution

– Definition of a linear equation and linear function.

In a linear equation the exponent of each variable is 1 and the variables may not be multiplied together. The graph of a linear equation is always a line.

In a linear function, each input value has a unique output value. In other words, for each point in domain, there is a unique value in the range of function. It can be written as $f (x) = m x + b$ , where $m$ and $b$ are real numbers.

– Given information.

The given equation is:

$x^{2} + y^{2} = 4$

– Check whether the equation is linear or not.

In the given equation the exponent of $v$ is $2$ and the exponent of $y$ is $2$ .

The equation $x^{2} + y^{2} = 4$ is not a linear equation because both $v$ and $y$ has an exponent other than $1$ .

Thus,the required answer is 鈥淣o鈥� because the equation $x^{2} + y^{2} = 4$ is not a linear equation
