Anything that has mass and takes up space
9/-12 is an obvious answer to eliminate as the numerator is not negative and the denominator is not positive. -15/20 simplified is -3/4, so you have to find a similar fraction. This means that D and A are eliminate and leaves you with C as the answer.
The equation of a line that is perpendicular to -9x = 15 - 3y is y = -1/3(x) + c.
Given:
-9x = 15 - 3y
3y = 15+9x
divide by 3 on both sides
3y/3 = 15/3 + 9x/3
y = 3x + 5
m = 3
Perpendicular slope m1 = -1/m
= -1/3
substitute m value in y = m1x +c
y = -1/3(x) + c.
Therefore the equation of a line that is perpendicular to -9x = 15 - 3y is y = -1/3(x) + c.
