Question

The distance of the point P (3, - 4) from the origin is
(a) 7 units (b) 5 units (c)4 units
(d) 3 units

Answer 1

Distance of the point P(x, y) from origin O(0, 0) = sqrt((x)^2 + (y)^2)

Distance of point P (3, -4) from origin = sqrt((3)^2 + (-4)^2)

Distance of point P (3, -4) from origin = sqrt(9 + 16) = sqrt(25) = 5

Distance of point P (3, -4) from origin = 5 units ——> Answer

Answer 2

Answer:

$(b) \: 5 \: units \: is \: the \: correct \: answer$

Step-by-step explanation:

Solution:

Correct option is (b)

Distance of point (−3,4) from the origin

=Distance of point (−3,4) from (0,0)

Distance formula=sq root(x2−x1)^2+(y2−y1)^2

=sq root(−3−0)2+(4−0)2

=9+16=25=5units
