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
