How do you find slope ?

Answer 1

if you have a slanted line, draw a right triangle with the line as hypotenuse.

Looking at the triangle, the slope of the line is the height/width.

In the x-y plane,

slope is ∆y/∆x

That is, it tells how fast y is changing as x changes. If y increases by 3 every time x increases by 2, the slope is 3/2.

If y decreases as x increases, the slop e is negative.
