An ordered pair (x, y) is a solution to the linear equation Ax + By = C, if the equation is a true statement when the x- and y-values of the ordered pair are substituted into the equation. The x-intercept is the point, (a, 0), where the graph crosses the x-axis. Starting with the point on the left, sketch a right triangle, going from the first point to the second point.
