A direct variation function contains the points (–9, –3) and (–12, –4). Which equation represents the function? y = –3x, y = equals StartFraction x Over 3 EndFraction. y = equals StartFraction x Over 3 EndFraction. y = 3x

y=3/4x

Step-by-step explanation:

Better known as C.

I chose this answer choice because I pulled up a graphing calculator and the result I got was y=3/4x (aka, C)

d

step-by-step explanation:

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d
