Question

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

Answer 1

Answer:

The equation which represents the  function is given by,

x = 3y .

Step-by-step explanation:

The direct variation function contains the points, (-9, -3) and (-12, -4).

Here,

$\frac {-9}{-3} = \frac {-12}{-4}$ = 3

So, the equation which represents the  function is given by,

x = 3y .

Answer 2

Answer:

x = 3y
