Answer:
-2
Step-by-step explanation:
residual value = measured value - predicted value (from the line of best fit)

0 - 2 = -2
The correct answer should be nine
Answer:
( 11/2, 5 ) !
Step-by-step explanation:
Refer to the picture!
Combine like terms:
subtract x from both sides to get
2x+5=14
subtract 5
2x=9
isolate x:
divide 2 from both sides to isolate x
x=9/2
that's your final answer. unless your teacher wants you to put it in decimal form in which all you do is divide 9÷2.
