WebSep 27, 2024 · For example, consider the following system of linear equations in two variables. 2 x + y = − 8 x − y = − 1. Let’s graph these using slope-intercept form on the same set of axes. Remember that slope-intercept form looks like y. First, solve for y in 2 x + y = − 8. 2 x + y = − 8 y = − 2 x − 8.
