State whether the statements are true or false.
The equation of the line joining the point (3, 5) to the point of intersection of the lines 4x + y – 1 = 0 and 7x – 3y – 35 = 0 is equidistant from the points (0, 0) and (8, 34).
Given two lines are:
4x + y - 1 = 0 …(i)
and 7x - 3y -35 = 0 …(ii)
Now, point of intersection of these lines can be find out as:
Multiplying eq. (i) by 3, we get
12x + 3y – 3 = 0 …(iii)
On adding eq. (ii) and (iii), we get
7x – 3y – 35 + 12x + 3y – 3 = 0
⇒ 19x – 38 = 0
⇒ 19x = 38
⇒ x = 2
On putting value of x in (i), we get
4(2) + y – 1 = 0
⇒ 8 + y – 1 = 0
⇒ y = -7
So, the point of intersection of given two lines is:
(x, y) = (2, -7)
Now, we have to find the equation of the line joining the point (3, 5) and (2, -7).
Again, equation of line is given by:
![]()
![]()
![]()
⇒ y – 5 = 12(x – 3)
⇒ y – 5 = 12x – 36
⇒ 12x – y – 36 + 5 = 0
⇒ 12x – y – 31 = 0 …(iv)
Now, the distance of eq. (iv) from the point (0, 0) is

![]()
![]()
Now, the distance of eq. (iv) from the point (8, 34) is

![]()
![]()
Hence, the equation of line 12x – y – 31 = 0 is equidistant from (0, 0) and (8, 34)
Hence, the given statement is TRUE
