Answer:
This is an experiment because a treatment was applied to a group.
Step-by-step explanation:
This is because it cannot be a survey since the children are taking a test, which has a hypothesis. Hope you get this right. I took the test and got right.
<span>the unit rate corresponds to the proportional relationship
shown in the graph is equivalent to the slope of the line. Which can be solve
using the formula:</span>
m = (
y1 – y2 )/ ( x1 – x2 )
m = (
0 – 9 ) / ( 0 – 6)
<span>m =
3/2</span>
Yes and for a. You can just put y=x [y=1x is bascually the same but just the 1 isnt needed]
I bealive if it is the nature of the slope in unison comparing y-intercept elgebra it is Y=3x-3/4
99.9 is the answer is that ok
