where a, b, c and d represent numbers. For example, \(\text{x = 3}\), \(\text{y = -7}\), \(\text{y = 5x + 11}\) Lines in the form \(\text{x = a}\) will always be ...

Quadratic graph lines are U- or Ո-shaped, which is called a parabola. A linear graph can be drawn using only three points. A quadratic graph is a curve, so more points are plotted to support accuracy.

Horizontal lines run left to right, parallel to the horizon, with slope 0 and equation y = k. Vertical lines run top to bottom, perpendicular to the horizon, with undefined slope and equation x = k.
