Answer:
option C.
Step-by-step explanation:
option C is the correct answer.
Direct variation: y = kx .........where k is constant.
10 = k * -5
k = -2
Then check if all are linear and matches.
y = -2 * -4
y = 8 ...matches.
then
y = -2 * -3
y = 6 ........matches
then
y = -2 * -2
y = 4 ........matches
then
y = -2*-1
y = 2 ......matches as well. so direct variation.
