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:

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
