The ordinate ofa point A on the y-axis is 5 and B has coordinates(-3.

1.	The ordinate ofa point A on the y-axis is 5 and B has coordinates(-3. I, then find the length of AB.
Answer» A is on y axis and it's ordinate is 5So 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..

Answer»

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