Question

find ordinate of a point A and y axis is 5 and B have co-ordinate (-3,1) . find the length of AB ​

Answer 1

Answer:

5

Step-by-step explanation:

A is on y axis and it's ordinate is 5

So coordinates of A is (0,5)

and coordinates of B is (-3,1)

Length of AB can be found out by using the distance formula

= √【(x1 -x2)^2 + (y1 -y2)^2】

= √【(-3-0)^2 + (1-5)^2】

=√【9 + 16】

=√25

=5

So length of AB is 5 units..
