X=29 and y=10
You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.
Answer:
The equation is not a linear function.
There's a strong negative association between the two variables.
Answer: B
Step-by-step explanation: if you divide 27/30 by 3 you get 9/10
