## Teaching how to find slope from two points easily.

The formula for determining the slope of a straight line having (a1, b1) and (a2, b2) as coordinate points is m = (b2-b1) / (a2-a1) or m = (b1-b2) / (a2-a1) where m represents the slope of that line and a and b represents coordinates of X-axis and Y-axis respectively.

Steps to find a straight line’s slope:

- Identity (a1, b1) and (a2, b2) from the given coordinates of the lines.
- After this calculation (a2-a1) and (b2-b1).
- Place this difference in the “m = (b2-b1) / (a2-a1)” formula.
- Complete the final calculation.

Q. Determine the slope of a straight line having (2,4) and (3,6) as its coordinates:

Solution:

a1 = 2, a2 = 3, b1 = 4, and b2 = 6.

b2-b1 = 6-4 = 2

a2-a1 = 3-1...
