Problema Solution
find all values of y such that the distance between (2,y)and (-10,3)is 13
Answer provided by our tutors
The distance 'd' between (x1,y1) and (x2,y2) is calculated by the formula
d=√((x2−x1)^2+(y2−y1)^2)
d^2 = (x2−x1)^2+(y2−y1)^2
In our case
d = 13
(x1, y1) = (2, y)
(x2, y2) = (-10, 3)
13^2 = (-10 - 2)^2 + (3 - y)^2
144 + (3 - y)^2 = 169
