Triangle abc has vertices of a(–6, 7), b(4, –1), and c(–2, –9). find the length of the median from angle b in triangle abc

  8

Step-by-step explanation:

The median is the segment from vertex B to the midpoint of AC. That midpoint (D) is ...

  D = (A + C)/2 = ((-6, 7) +(-2, -9))/2 = (-8, -2)/2

  D = (-4, -1)

The length of the midpoint is the length of the segment DB between (-4, -1) and (4, -1). These points both have the same y-coordinate, so the length is the difference of x-coordinates: 4 -(-4) = 8.

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

i believe that the answer is

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

hope this !
