Weby=mx+b. In this equation, 'm' is the slope and 'b' is the y-intercept. To graph a line from a slope-intercept equation, take the value of the slope and put it over 1. For example, if the slope was 5, the slope would be 5/1. Next graph the y-intercept, take the number that is the y-intercept, and graph that number on the graph. WebSolving linear equations A linear equation is an equation that contains letters and numbers, for example \(3x + 10 = 16\) . It does not contain any \(x^2\) or \(x^3\) terms.

WebSystems of linear equations are a common and applicable subset of systems of equations. In the case of two variables, these systems can be thought of as lines drawn in two-dimensional space. If all lines converge to a common point, the system is said to be consistent and has a solution at this point of intersection.
