How Do You Write an Equation of a Line in Slope-Intercept Form If You Have Two Points?
Given two points on a line, write an equation in slope-intercept form. But what's the slope? Oh, you have to figure out the slope first. That can be done given the two points. Just use the rise over run slope formula. This isn't so hard...

How Do You Put an Equation in Standard Form Into Slope-Intercept or Point-Slope Form?
Given a linear equation, rewrite it in different forms. No matter what form a linear equation is given in, it can be converted to the other forms. So that means every linear equation can be written in standard form, point-slope form and...

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...

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...
