A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation. STEP 1 - Draw ...

One line, 𝒚 = 3 - 4𝒙, has a negative gradient. Each positive gradient is multiplied by the negative gradient to find if any product is -1. ¼ × -4 = -1.

This paper is mainly concerned with the realizability of a set of n integers as the degrees of vertices of an n-vertex linear graph. Other related problems, such as when a set of integers is ...
