I tried graphing the points, and I formed a right triangle.

short leg = 6-1 = 5
Hypotenuse = 13
long leg = ?

a² + b² = c²
a² + 5² = 13²
a² = 13² - 5²
a² = 169 - 25
a² = 144
√a² = √144
a = 12

S has coordinates (6,y) = y = 12 + 3 = 15
S (6,15)

The required possible value of y are 15 and -9.

Step-by-step explanation: Given that the point R has co-ordinates (1,3) and point S has coordinates (6,y). Also, the distance from R to S is 13 units.

We are to find the possible values of y.

Distance formula : The distance between the points (a, b) and (c, d) is given by

$d=\sqrt{(c-a)^2+(d-b)^2}.$

Therefore, we get

$\sqrt{(6-1)^2+(y-3)^2}=13\\\\\Rightarrow 25+(y-3)^2=169~~~~~~~~~~~~[\textup{Squaring both sides}]\\\\\Rightarrow (y-3)^2=169-25\\\\\Rightarrow (y-3)^2=144\\\\\Rightarrow y-3=\pm12~~~~~~~~~~~~~~~~~~~[\textup{Taking square root on both sides}]\\\\\Rightarrow y=12+3,~~-12+3\\\\\Rightarrow y=15,-9.$

Thus, the required possible value of y are 15 and -9.
