Graphing Linear Equalities using a table

(1) Graphing Linear Equations, Part 1, Mr. Perez & Charlie
In the first problem, when the line is graphed, you notice that the line crosses the y-axis at (0,5), and crosses the x-axis at (5,0).  The points at which the line crosses the axes (pl. of axis) are called the x-intercept and the y-intercept.

(2) Graphing Linear Equations, Part 2, Mr. Perez & Charlie
Problem 2 continues in this video, and you can see the line crosses the x and y axes.
The x-intercept is at (3,0) and the y-intercept is at (0,-2).
Problem 3 shows the x-intercept at (6,0) and the y-intercept at (0,-4).
