Question

Which points are 3.5 units apart?
(7.5, 1.2) and (7.5, –2.3)
(7.5, –3.5) and (7.5, 3.5)
(7.5, 1.2) and (7.5, 2.3)
(7.5, –3.5) and (7.5, 7)

Answer 1

SOLUTION

TO CHOOSE THE CORRECT OPTION

The points are 3.5 units apart

• (7.5, 1.2) and (7.5, –2.3)

• (7.5, –3.5) and (7.5, 3.5)

• (7.5, 1.2) and (7.5, 2.3)

• (7.5, –3.5) and (7.5, 7)

CONCEPT TO BE IMPLEMENTED

If two points are of the form (a, b) & (a, c) then the distance between the two points are

$= \sf{ | \: c - b \: | \: \: unit }$

EVALUATION

Here all the points are of the form (a, b) & (a, c)

Since abscissa are same

So the points lies on a line parallel to Y axis

Here the distance between the points (7.5, 1.2) and (7.5, –2.3) is

$= \sf{ | \: 1.2 - ( - 2.3) \: | \: \: unit}$

$= \sf{ | \: 1.2 + 2.3 \: | \: \: unit}$

$= \sf{ 3.5 \: \: unit}$

FINAL ANSWER

The correct option is

(7.5, 1.2) and (7.5, –2.3)
