Question

Find the value of y ,if the distance between the points (2,y) and (-4,5) is 10 pls explain it

Answer 1

Step-by-step explanation:

take point (2,y)as A and (-4,5) as B and the given distance is 10 units. Use formula of coordinate geometry √(x2-x1)^2+(y2-y1)^2. root for both squares

if u use the formula u will get the quadratic equation y^2-10y-39

which u will get y=13 or y =-3

Answer 2

Hey,your answer is 13 and -3.

Hope this helps you a lot..
