1. Graphs help you solve equations, and equations help you solve graphs. Because <span>the graph is a diagram of the equation, showing at its simplest the y answer for each value of x. 2. </span>You have to solve for y, graph it, and then find where the lines intersect.You can take a table and put in all the x and y values. Then you graph it.. And see where it intersects because usually these equations are lines. Also you'd wanna solve for slope-intercept form(y = mx + b)
