Start with point-slope form, where 
is the slope and 
is a known point on the line.
Substitute in the known values.
Distribute the 
to the 
.
Add 
to both sides.
Here's the key:
Any radius that's perpendicular to a chord, bisects the chord.
So the piece of a radius that's perpendicular to the chord bisects it,
and the part of the chord that forms a side of the triangle is also 6.5 .
The triangle is a right triangle, and its hypotenuse is a radius of the circle.
the diameter of the circle is 16, so the length of the radius is 8 .
So now you know the length of the hypotenuse and one leg of a right
triangle, and side 'x' is the other leg.
This is where Pythagoras comes in.
(hypotenuse)² = (one leg)² + (the other leg)²
(8)² = (6.5)² + x²
64 = 42.25 + x²
x² = 64 - 42.25
x² = √21.75
x = about 4.664... (looks like choice-A)

Funny story actually, i actually was making cookies at my house once and i put the cookie dough in the microwave for two minutes which resulted in the plate exploding: that was my mothers plate that she cared about alot.
