Answer:
A
Step-by-step explanation:
A
I think S=0... Hoped this helped!
The linear rule should look like this y=a*x+b
As the function graph goes through the (0,0) point, the equation 0=a*0+b <=> b=0 must be true.
Now we only need to find a, using one of the points given. With (-4, 16):
16=-4*a <=> a=16/-4 <=> a= -4
So the rule looks the following way:
f(x)= -4*x
6 and 3/4 divided by 1/2
27/4 divided by 1/2
27/4 * 2/1 = 27/2 = 13 and 1/2
