Which equation is a point slope form equation for line ab?
lara [203]

we have point (1,-1)

and point  (-3,5)

 slope =(y2-y1)/(x2-x1)

   m = (5-(-1))/(-3-(1))

  m = 6/(-3-1)

   m = 6/-4

   m = -3/2

point slope form

y-y1 = m(x-x1)

y-(-1) =-3/2(x-(1))

y+1=-3/2(x-1)

Choice B

write the equation of the ellipse using the given information: the ellipse has foci (0,3) and (0,-3) and major vertices (0,5) an
svetlana [45]

Answer: (x^2)/16 + (y^2)/25 = 1

Step-by-step explanation:

According to the problem we can figure out that the center of the ellipse is (0,0).

Since the foci is (0,3) and (0,-3) we know that the value of c is 3. The major vertices are (0,5) and (0,-5) so the value of a is 5.

If we put this into the equation a^2=b^2 + c^2, we get 25=9+ b^2

We get b^2 is 16

Now since we know that the ellipse is vertical because the x value didn’t change, we know that the b^2 value comes first in the equation. Then the a^2 value which is 25.
