Answer:
y = 2
Step-by-step explanation:
use slope formula:
(4 - y) / (3 - 10) = -2/7
4-y / -7 = -2 /7
cross-multiply:
7(4 - y) = (-7)(-2)
28 - 7y = 14
-7y = -14
y = 2
6y = (x - 4)² + 34/3
6x = (y - 4)² + 34/3
(y - 4)² = 6x - 34/3
y - 4 = √(6x - 34/3)
y = 4 +- √(6x - 34/3)

r has to be less than 5, now doesn't it
