Four points can produce a polynomial of at most the third order - a cubic. It is, of course, possible that the 4 points are collinear.
The coordinates of every point on the graph, and no other points, are solutions of the equation.
You can either measure or estimate the coordinates visually from the graph, or solve the equation underlying the graph.
The graph (on Cartesian coordinates) of a quadratic equation is a parabola.
You calculate the coordinates using a fraction!
Just took the vocab test the answer is graph.
By the process of plotting.

The coordinates of the points on the curve represent solutions of the equation.
It is the locus of all points whose coordinates satisfy the equation of the line.
Select any value for one of the variables in the graph and solve the equation to get the other variable.
Yes, I'm confident of that.
A cubic graph!
