The distance between two points is 10 units, if the coordinates of one of the endpoints are (4, -7), find x if the coordinates o
f the other endpoint are (x, 1).
1 answer:
Answer:
10
Step-by-step explanation:
let the distance = d
d² = (x2-x1)² + (y2-y1)²
=>
10²= (x-4)²+(1+7)²
100 = (x-4)²+64
(x-4)²=100-64
= 36
x-4 = √36
x-4=6
x= 6+4
x= 10
