Question

16. The distance between the line 2x + 4 = 0 and x-5=0 is
(a) 9 units
(b) 1 unit
(c) 5 units
(d) 7 units​

Answer 1

The distance between the line 2x + 4 = 0 and x-5=0 is

(d) 7 units

For the first line, 2x + 4 = 0,

we equate to get, x = -4/2 = -2

There is no y coordinate.

So, first point (-2,0)

For the second point x - 5 = 0,

we equate to get, x = 5

There is no y coordinate.

So, second point (5,0)

The distance between the two points = √[{5-(-2)}² + (0-0)²]

= √(5+2)²

= √7²

= 7 units

Option (D) is correct.

Answer 2

Answer:

(d) 7 units

The correct answer is mentioned above
