What is the equation of the parabola that has a vertex at

(- 18, - 12)

and passes through point

(- 3, 7)

https://socratic.org/questions/what-is-the-equation-of-the-parabola-that-has-a-vertex-at-18-12-and-passes-throu

y = \frac{1 9}{2 2 5} (x + 18)^{2} - 12

Explanation: Use the general quadratic formula,

y = a (x - b)^{2} + c

Since the vertex ...

How do you find the midpoint of the line segment joining the points

P (- 4, 6)

Q (- 8, - 12)

https://socratic.org/questions/how-do-you-find-the-midpoint-of-the-line-segment-joining-the-points-p-4-6-and-q-

See a solution process below: Explanation: The formula to find the mid-point of a line segment give the two end points is:

M = (\frac{( x _{1} ) + ( x _{2} )}{2}, \frac{( y _{1} ) + ( y _{2} )}{2})

What is the equation of the parabola that has a vertex at

(- 12, - 11)

and passes through point

(- 9, 16)

https://socratic.org/questions/what-is-the-equation-of-the-parabola-that-has-a-vertex-at-12-11-and-passes-throu

y = 3 x^{2} + 72 x + 421

the equation of a parabola in vertex form

(\overline{\underline{∣ ∣ ∣ ∣ ∣ (\frac{2}{2}) (y = a (x - h)^{2} + k) (\frac{2}{2}) ∣ ∣ ∣ ∣ ∣}})

What is the slope of any line perpendicular to the line passing through

(- 8, 2)

(- 12, - 20)

https://socratic.org/questions/what-is-the-slope-of-any-line-perpendicular-to-the-line-passing-through-8-2-and-

- \frac{2}{1 1}

Explanation: The slope of the line passing through (-8,2)and (-12.-20)is

\frac{- 2 0 - 2}{- 1 2 + 8} = - \frac{2 2}{- 4} = \frac{1 1}{2}
