Question

Write in standard and vertex form( show your work)
3. (-1, 10), (2, 4), (3,-6)

Answer 1

standard form = 2x + y = 12

vertex form =
`y = -2(x-0)^2 + 12`

Explanation:

slope-intercept form =
`y = -2x^2 + 12`

standard form equation:
`Ax + By = C`

standard form = 2x + y = 12

vertex form equation:
`y = a(x-h)^2 + k`

a = -2 , h = 0 , k = 12

vertex form =
`y = -2(x-0)^2 + 12`
