Question

Find tge distance ot tge points a(5,12)from y axis

Answer 1

Assuming a point to be on y axis with coordinate (0,12).

The other point “a” with coordinate (5,12) is perpendicular to y axis.

Distance formula

→ $\mathsf{\sqrt{{(x_2 - x_1)}^{2}+{(y_2 - y_1)}^{2}}}$

→ $\mathsf{\sqrt{{(5 - 0)}^{2} + ({12 - 12)}^{2}}}$

→ $\mathsf{\sqrt{ {5}^{2}} = 5}$

Hence the distance of point “a” from y axis is 5 units.

Answer : 5 units

Here,

• $\mathsf{x_2 = 5}$
• $\mathsf{x_1 = 0}$
• $\mathsf{y_2 = 12}$
• $\mathsf{y_1 = 12}$

Answer 2

Answer

(x 2 −x 1 ) 2 +(y 2 −y 1 ) 2

(5−0) 2 +(12−12) 2

$\mathsf{\sqrt{ {5}^{2}} = 5}$

Answer=5units
