# Distance of a point from a line

**Question**

Calculate the perpendicular distance of the following points to the line of 2y = 5x + 1.

- (3,1)
- (0,1)
- (3,0)

**Answer**

- 2.600
- 0.186
- 2.971

*Note:*

The equation of a line of ax + by + c = 0 and a point located at (m,n). Then, the perpendicular distance of the point from the line can be calculated by using the formula below.

*d = |am + bn + c|/√(a ^{2} + b^{2})*
