# What is the slope of a line passing through (3, 4) and (5, 8)?

**Solution:**

Slope of line joining two points (x_{1}, y_{1}) and (x_{2}, y_{2}) is m = (y_{2} - y_{1}) / (x_{2} - x_{1})

Here, (x_{1}, y_{1}) = (3, 4) and (x_{2}, y_{2}) = (5, 8)

ஃ slope = m = (8 - 4) / (5 - 3)

m = 4 / 2 = 2

**Note:**

Slope of the line can also be calculated if the angle(Ө) made by the line with positive direction of x axis is given using slope = m = tan Ө

**Example**: If the line makes an angle 60° with the positive direction of the x axis then find the slope.

**Solution:**

Slope of line = m = tan 60° = √3

## What is the slope of a line passing through (3, 4) and (5, 8)?

**Summary: **

The slope of a line passing through (3, 4) and (5, 8) is 2
