Question

2. What is the distance between the lines 2x + 4=0 and x-5=0? (a) 1 unit (b) 2 units (c) 5 units (d) 7 units​

Answer 1

Answer:

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
