You have to solve it or if the answer is provided to you look at the y axis which is the one on the right of the graph. If the numbers form a pattern then its linear if there not... Well you can figure that out. It works for me most of the time and on a test one of five was wrong on this method.

how do we find linear feet or inche
(y2-y1)(x2-x1) you plug in the equation to this formula and thats ur answer!
A linear equation has no higher powers than 1. This is linear.
You can multiply both sides of an equation by a non-zero constant.
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.
