Answer:
yes
Step-by-step explanation:
Direct variation is represented as
y = kx, where k is a constant.
We can rewrite y - x = 0 as
y = x (add x to both sides)
This can be looked at as
y = (1)x , so this is a direct variation relationship where k = 1
x = {3, 5}
x=1 y=-5
7(5x-2y=15) ---> 35x-14y=105
2(7x+7y=-28) --> + <u>14x+14y=-56</u>
49x=49 --->x=1
5(1)-2y=15 ---> 5-2y=15 ---> -2y=10 ---> y=-5
The value of f(0) is Option (A) : - 2
