Someone please help!! Thanks

scalene right triangle

i believe that the answer is

b. y-1=-2(x-4)

hope this !

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
