Answer:

A.

Step-by-step explanation:

Slope = y2-y1/x2-x1

(2,-4) = (x1,y1)

(4,2) = (x2,y2)

Slope = (2+4)/(4-2)

          = 6/2

          = 3

Y=mx+b   [Plugging (4,2) into this]

2 = 3×4 +b

2 = 12 + b

b = -10

What are the vertices of the following graph?
tatuchka [14]

The graph represent a horizontal ellipse with center ,(h,k)=(-1,3)

Length of major axis, 2a =8-(-10) = 18

Therefore, a = 9

And length of minor axis, 2b =5-1 =4

Therefore b=2

The formula that we have to use to find the vertices

(h+-a,k)

(-1+-9,3) = (-1-9,3),(-1+9,3) = (-10,3),(8,3)
