How Do You Write an Equation of a Line in Slope-Intercept Form If You Have One Point and a Parallel Line?
This may seem like a complicated problem, finding an equation that is parallel to the given equation and passing through a given point, and writing it in slope-intercept form, but it's really not. It's just a matter of rearranging...

What Are Parallel Lines?
What kind of lines have equal slopes, equal incline or decline, and equal rise over run? Yes! Parallel lines. What are parallel lines? They are lines on a graph that go on and on and on forever and never touch each other. Watch this...

Slope Intercept Formula
If you are a line then you can be written in slope-intercept form. Have students view this video to understand what slope-intercept does, how it works and why the y is so important. This video is very explicit and clear.

How Do You Find the X- and Y-Intercepts of a Line If You Have a Graph?
The x-intercept is the point at which the line of the equation crosses the x-axis. The y-intercept is the point at which the line of the same equation crosses the y-axis. It's as easy as that. Look at your graph and note these locations.

What's Standard Form of a Linear Equation?
How many ways can you write a linear equation? Yep, lots! Each form has it's purpose in the world of Algebra, so do you know how to write it in standard form? Ax+by=c. This is what standard form looks like. Can you rearrange the given...

How Can You Tell If You Have a Linear Equation?
Is it a linear equation? Does it fit into the standard form of a linear equation? This example does not fit into the standard form and is not a linear equation. The end. I would have preferred then to have the instructor also show an...
