Solutions to a System of Equations - Graphically I

Introduction

A system of equations can be solved graphically by drawing the graphs of both equations on the same coordinate plane. The solution is found by looking for the point where the graphs meet. Graph...

Ria got a homework problem to solve the linear equations y = x + 2 and y = 2x − 1 graphically.

For the first equation, she chooses values 0, 1, 2, and 3 for x and finds the corresponding values of y by substituting the x value into the equation and solving for y. She plots these points on a graph and draws a straight line.

Next, she ...
