What do the following two equations represent?

-2x+4y = 5−2x+4y=5minus, 2, x, plus, 4, y, equals, 5

-12x-6y = 1−12x−6y=1

(choice a)
a
equal lines

(choice b)
b
parallel lines

(choice c)
c
perpendicular lines

(choice d)
d
none of the above

C. Perpendicular lines

Step-by-step explanation:

The given system is:

We need to rewrite both lines in slope-intercept form.

This implies:

Simplify:

The slope of the first line is the negative reciprocal of the slope of the second line.

The two lines are perpendicular

The third option is correct

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
