Use a graph to approximate the solution of a system of linear equations or inequalities in two variables with and without technology.
Remarks
Example 1: Graph 3y - x = 0 and 2x + 4y = 15 on the same coordinate system. Determine whether the lines intersect. If so, find the point of intersection.Example 2: Graph the following inequalities and shade the region (if any) on the coordinate plane where both inequalities are true: y ≤ 4 and x + y ≤ 5
Example 3: Approximate the solution, if any, for the following system of linear equations:
