Using the linear regression calculator, we have that,
<h3>The linear equation that best fits the data is

</h3>
Thus, option A is correct.
Answer:
x= 2
Step-by-step explanation:
so expand the left side of the equation
9x+9= 25+x
and then group like terms( subtract 9 from both sides and also do same with x.
9x-x= 25-9
8x= 16
divide by 8 on both sides.
x=2
2x+3y is the expression simplified
