How Do You Check if a Point is on a Line If You Have an Equation?

How Do You Check if a Point is on a Line If You Have an Equation?

Note:

Wondering if a point is part of the equation of a line? Got the equation of the line but no graph? No problem! Just take that point and plug it into the equation and simplify. If you end up with a true statement, the point is indeed part of the equation. If you end up with a false statement, then that point is not part of the equation. See this process first-hand in this tutorial!

      What's Slope-Intercept Form of a Linear Equation?

      When you're learning about linear equations, you're bound to run into the point-slope form of a line. This form is quite useful in creating an equation of a line if you're given the slope and a point on the line. Watch this tutorial, and learn about the point-slope form of a line!
