Question

What is the formula for the slope of a line when you have two points?

Answer 1

Question:

Which formula is used in finding the slope of two points of a line is given?​

Answer:

m=y2−y1x2−x1 m = y 2 − y 1 x 2 − x 1

Explanation:

We use the two points of the line and this formula to find the slope of the line using rise and run. It is another version of another formula named, m=riserun m = rise run. The slope will definitely equal the rise divided by the run.

Answer 2

Given:

Slope and Two points

To find:

Equation of slope passing through two points

Solution:

Let the slope be m.

Let the two points be (x1,y1) and (x2,y2).

Slope = Change in y/ Change in x

m = (y2 - y1)/ (x2-x1)  

Hence, equation of slope passing through two points is m = (y2 - y1)/ (x2-x1)
