Question

Which of the following is a linear equation? ​

Answer 1

Answer:

1 one is a linear equation

Step-by-step explanation:

because it is in the form of ax2+bx+c

Answer 2

Key features of all linear equations include:

1. A linear equation has only one or two variables.
2. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
3. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all the points lie on the same line. The graph of a linear equation is a straight line.

According to these rules, an example of a linear equation is $\frac{z-2}{4} = \frac{3z+5}{5}$, which is the answer to your question.
