This video covers the process of graphing points and then connecting them with a segment or a line. If you are in algebra and need equations of lines, click here.
Graphing Basic X-Y Shapes
This video introduces you to the concept of shapes on the X-Y plane, such as if they give you the center and radius of a circle and ask you to draw the graph. (If you need equations of circles and parabolas, try this.)
X-Intercept & Y-Intercept
This video introduces X-intercepts and y-intercepts, both what they are and how to find them.
Are The Points Collinear?
This video introduces collinearity, then explains how to figure out whether x-y points are collinear or not, using both a graphing method and also an equations version for all of you algebra fans out there.
How To Find X-Intercepts and Y-Intercepts
This video covers the process of solving for the x- and y-intercepts of an equation, whether it's a line or a parabola. X-intercepts are also known as the "zeroes" of a function, if you're looking for that.
