Question

The vertex is 2,9 and the points are -2,5. and you have to convert it to y-k=a(x-h)^2

Answer 1

okay do u remember what are h and k?

Answer 2

the points right

Answer 3

well no they're coordinates of a point. Which point, do u remember that?

Answer 4

okay i get that the points that i put up there are h,k and i just want to see if i got the problem right because my teacher doesnt want us to have fractions soo yea

Answer 5

okay h and k are coordinates of the vertex, so:
h = 2, k = 9
a is the slope
to find the slope from two points (2,9) and (-2,5):
Slope = rise/run = (y-y1)/(x-x1) = (5 - 9)/(-2-2) = -4/-4=1

Answer 6

y-k=a(x-h)^2
y-9=1(x-2)^2, or
y-9=(x-2)^2
