Question

if A is a point on Y-axis whose ordinate is 4 and coordinate of Bis (-3,1),then find the distance of AB

Answer 1

A is the point (0,4) and B is (-3,1)

Distance AB = sqrt [ (0- -3)^2 + (4-1)^2 ]

= sqrt (9 + 9)

= sqrt 18

= 4.24 to nearest hundredth

Answer 2

For this question, you would have to use the distance formula. The answer is 5.
