Answer:

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes.

The exemplar equation has slope

9x - 3y = 18

- 3y = -9x + 18

y = 3x - 6

m = 3

so perpendicular slope will be -1/3

D has such a slope

3y = -x + 1

y = (-1/3)x + 1/3

What is 18/30 in simplest form?

qaws [65]

To simply this, you just divide the numerator and denominator by its GCF (Greatest common factor)

Factors of 18 : 1,2,3,6,9,18
Factors of 30 : 1,2,3,5,6,10,15,30
As you can see, the great common factors of 18 and 30 is 6.

So divide 18 by 6 and 30 by 6, and you get 3 and 5

Therefore, the simplest form is 3/5
