The ordinate of point on Y-axis is 5 and point B as coordinate (-3,1). Find the length of AB

The ordinate of point on Y-axis is 5 and point B as coordinate (-3,1).

1.	The ordinate of point on Y-axis is 5 and point B as coordinate (-3,1). Find the length of AB
Answer» Here, A\xa0{tex}\\rightarrow{/tex}(0,5) and B{tex}\\rightarrow{/tex}(-3, 1)AB =\xa0{tex}\\sqrt { \\left( x _ { 2 } - x _ { 1 } \\right) ^ { 2 } + \\left( y _ { 2 } - y _ { 1 } \\right) ^ { 2 } }{/tex}{tex}= \\sqrt { ( - 3 - 0 ) ^ { 2 } + ( 1 - 5 ) ^ { 2 } }{/tex}{tex}= \\sqrt { 9 + 16 }{/tex}{tex}= \\sqrt { 25 }{/tex}= 5 units
