Adirect variation function contains the points (–8, –6) and (12, 9). which equation represents the function? y = –k equals negative startfraction 4 over 3 endfraction x. x y = –k equals negative startfraction 3 over 4 endfraction x. x y = k equals startfraction 3 over 4 endfraction x. x y = k equals startfraction 4 over 3 endfraction x. x

For this case we have that by definition, a direct variation is of the form:

Where "k" is the constant of proportionality

If the following points belong to the variation (-8, -6) and (12,9) then we have to replace one of the points we find the value of "k":

Thus, the function is given by:

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
