Question

I think I have the answer but I'm not sure. Please help! I'll give a medal or whatever else.

Part A: What is the approximate y-intercept of the line of best fit and what does it represent? (5 points)

Part B: Write the equation for the line of best fit in slope-intercept form and use it to predict the number of games that could be won after 13 months of practice. (5 points)

Answer 1

For part A I have the y-intercept as 1 and it represents the number of games won. I just need help with part B :)

Answer 2

Y-intercept when x =0

Answer 3

The number of games won without practicing

Answer 4

The line of best fit
Find the slope

Answer 5

For any (x y) slope-intercept form
Y = m x + b where m is the slope and b = y-intercept

Answer 6

Part. C. Find y when x = 13

Answer 7

I'm having a hard time finding the slope because of where the points lie. The rise/run method isn't really working for me here. Can you help explain it? I can't figure it out

Answer 8

@triciaal I think the slope is 1? Because it's 4 over 4 which simplifies to 1. Would you agree or disagree?

Answer 9

Anyone still here?

Answer 10

Responding elsewhere

Answer 11

No worries. Take your time, I just wanted to make sure I wasn't alone haha

Answer 12

Let me get to the PC so I can use the draw. Easier for me than this Ipad

Answer 13

That's fine! Thank you
