Step-by-step explanation:
delta math
1/2 of the class are 5th and 4th
1/2 of 96= 48
1/4 of 48 =12
A proportional relationship is also a direct variation.
The general equation of direct cvariation is
y = kx,
where k is a number.
In your case, if k = -1, then y = kx becomes y = (-1)x which is the same as
y = -x
