I can't see the table, but you find the total amount that the entire fifth grade made and divide it by six. I would round it to the nearest hundredth.
your question is incomplete dear check it once
First, divide each side by 4 to get y alone on the left side.
y=-6/4x+2
The y intercept is 2
Since the denominator cannot be zero, you can set 4z+1=0 to find the excluded values.
4z+1=0
4z=-1
z=-1/4
And thus, z cannot equal -1/4
