Find the distance of the point (1, 2) from the straight line with slope 5 and passing through the point of intersection of x + 2y = 5 and x – 3y = 7.
Given:
Lines x + 2y = 5 and x – 3y = 7, slope = 5.
To find:
The distance of the point (1, 2) from the straight line with slope 5 and passing through the point of intersection of x + 2y = 5 and x – 3y = 7.
Concept Used:
Distance of a point from a line.
Explanation:
To find the point intersection of the lines x + 2y = 5 and x − 3y = 7, let us solve them.
⇒ x y
So, the equation of the line passing through with slope 5 is
⇒ 5y + 2 = 25x – 145
⇒ 25x – 5y – 147 = 0
Let d be the perpendicular distance from the point (1, 2) to the line 25x – 5y – 147 = 0
∴d
Hence, the required perpendicular distance is
