Answer:
A linear equation in two variables describes a relationship in which the value of one of the variables depends on the value of the other variable. In a linear equation in x and y, x is called the independent variable and y depends on it. We call y the dependent variable.
Stepbystep explanation:
A linear equation looks like any other equation. It is made up of two expressions set equal to each other. A linear equation is special because:
It has one or two variables.
No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
When you find pairs of values that make the linear equation true and plot those pairs on a coordinate grid, all of the points for any one equation lie on the same line. Linear equations graph as straight lines
