you have the best fit line so for 1 hour increase you can just plug in 1 into the equation and solve. Do it again for the third part.

anonymous · Answer

@Rhystic wait whats the second one ??

anonymous · Answer

@billj5  do you know this one?? i just need my answers checked

rhystic · Answer

again you just plug in 0 for x and solve.

anonymous · Answer

first one = -25.31
second one = 25.31
third one =14.53

anonymous · Answer

are those correct??

rhystic · Answer

no.. I didn't check your first or third but with 0 utilized in the second one you should just come out with 26.08

rhystic · Answer

25.38 for the first one. what equation are you utilizing ?

anonymous · Answer

y=-0.77(1)+26.08

rhystic · Answer

sorry meant 25.31 for the first.

rhystic · Answer

yeah you just had a negative sign in your first answer. the second one was wrong you utilized 1 instead of 0 and third one was correct.

anonymous · Answer
