It's the equation of a straight-line graph. Every point on the line is a solution of the equation. There are an infinite number of them.

A ( blank ) is a graph that shows data along a number line

No. The equation describes a straight line and the coordinates of any one of the infinitely many points on the line is a solution.

This is an equation of a straight line. A solution for two unknowns requires two (independent) equations; there is only one here. Every point that is on that line is a solution to the equation. So you can let x be any real number and find a corresponding y. This ordered pair (x,y) will be a solution to the equation as well as a point on the graph of the line.

The equation cannot be "solved", nor can it be simplified in any significant way. It is the equation of a line and the coordinates of any one of the infinite number of points on that line will be a solution to the equation.
