Which statement best explains the relationship between lines fg and hj?

they are perpendicular because their slopes are equal.
they are perpendicular because their slopes are negative reciprocals.
they are not perpendicular because their slopes are equal.
they are not perpendicular because their slopes are not negative reciprocals.

(D)

Step-by-step explanation:

From the figure, we have

The coordinates of the point F are: (-4,1).

The coordinates of the point G are: (0,-2)

The coordinates of the point J are: (0,4) and

The coordinates of the point H are: (-4,-2).

Now, the slope of the line FG is :

And, the slope of the line HJ is:

Now,

which is not possible, thus They are not perpendicular because their slopes are not negative reciprocals.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
