3. Write the equation of each parabola in vertex form with a vertex (2, 1) and point (4, -3). Vertex = (h, k) = (2, 1) – y = a (x – -3= a(4- -3 = al = 4a → a= - y = (x- )2 + )2 + )2 + )2 + + + - +​

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
