Answer:- 0.6 units
Given the linear equation,
- 3x - 4y - 26 = 0
We have to find the perpendicular distance of the point (3, -5) from the line 3x - 4y - 26 = 0
Comparing the given linear with the standard form of quadratic equation i.e., Ax + By + C = 0
We get,
- A = 3 , B = -4 , C = -26
And regarding the point (3, -5), we have
- x₁ = 3 , y₁ = -5
Using the formula to calculate distance of a point from a line as.
⇒ d = | Ax₁ + By₁ + C | / {√(A² + B²) }
⇒ d = | 3×3 + -4 × -5 + (-26) | / { √(3² + (-4)²) }
⇒ d = | 9 + 20 - 26 | / √(9 + 16)
⇒ d = | 29 - 26 | / √25
⇒ d = 3 / 5
⇒ d = 0.6 units
