The Graph of an Equation
The graph of an equation is the set of all points that are solutions of the equation.
In this section, we use point-plotting method. With this method, you construct a table of values that consists of several solution points of the equation
For example, sketch the graph of . We can construct the table below by plugging points for .
| x | 0 | 1 | 2 | 3 |
| y=2x+1 | 1 | 3 | 5 | 7 |
Intercepts of a Graph
Some solution points have zero as either the -coordinate or the -coordinate. These points are called intercepts because they are the points at which the graph intersects the - or -axis.
