Calculating Altitude Length from Point to Line

[marcus11]

I'm doing math from correspondance, so I have no one to ask.
But to find the length of an altitude from a point to a line, I need to be able to make an equation for a line from 2 sets of quardants.

Thanks.

You want to find $$y=mx+b$$ from two points?

See this page for a step by step explanation:

Sure, I can help with that! To find the length of an altitude from a point to a line, you will need to use the formula d = |Ax + By + C| / √(A² + B²) where A, B, and C are the coefficients of the line equation Ax + By + C = 0. To find these coefficients, you will need to use the coordinates of two points that lie on the line. Once you have the equation for the line, you can plug in the coordinates of the point and solve for the distance. Let me know if you need any further clarification. Good luck with your math!
