Answer:
y - 7 = (x + 8)
Step-by-step explanation:
Use the slope formula to work out the slope
Then pick one point to insert into the formula y - y1 = m(x - x1)
The parabola with with a vertex at (-4,-2) represents any member of parabolas with the equation where
is any real number with the exception that
.
The reason any equation of the form works is that there are an infinite number of parabolas with a vertex at (-4,-2). All of these parabolas are formed by applying some transformation that involves a vertical translation of -2 and a horizontal translation of -4 on the parabola
. The different variations are archived by varying the constant
. When
is negative, the parabolas will face downwards. When
is negative, the parabolas will be face downwards.
