the coordinates of a point a on y axis is 5 and b has coordinates(-3,1).Find the lenght of ab

Open in App

Solution

Dear student
$Coordinates of point A = (0, 5) Coordinates of point B = (- 3, 1) Length of AB = \sqrt{{(x_{2} - x_{1})}^{2} + {(y_{2} - y_{1})}^{2}} = \sqrt{{(- 3 - 0)}^{2} + {(1 - 5)}^{2}} = \sqrt{9 + 16} = \sqrt{25} = 5 units$
