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|/√(a2 + b2)
