Factor the polynomial completely.
Group and factor out the greatest common factor (GCF), then combine.
Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Answer:
neither
Step-by-step explanation:
Slope of the first line: (y2 -y1)/(x2-x1) = (3-(-5)/-1 = 8/-1 = -8
Slope of the second line: (2-3)/4-(-4) = -1/8
They are neither parallel nor perpendicular. In fact the two lines have different slope so they can’t be parallel. In addition the product of their slope is not -1, so they can’t be perpendicular,

From any proportion, we get another proportion by inverting the extremes (or the means):

= k
so we have:
2x=3k
2x+y=2k therefore:
3k+y=2k
y= - k
x=


= -

The corect answer is A. -3/2
or:

From any proportion, we get another proportion by inverting the extremes and the means:

We use a property of proportions:

where a, d are extremes and b,c are means and the product of the extremes equals the product of the means (a*d=b*c),
so we have

or

(you can check this also by "the product of the extremes equals the product of the means")
