If the distance between the points A(2, -2) and B(-1, x) is equal to 5, then the value of x is: (a)2 (b)-2 (c)1 (d)-1

Answer:

(a) 2

Step-by-step explanation:

We can assume this is a 3-4-5 triangle from the two given sides, 5 and 3(2--1) so then we know the y difference of the y coordinate should be + or - 4 from -2 giving us two solutions of 2 and -6 since this is a multiple choice and a is 2 he answer is 2
