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)

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 :)

The line of best fit
Find the slope
For any (x y) slope-intercept form
Y = m x + b where m is the slope and b = y-intercept
Part. C. Find y when x = 13
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
@triciaal I think the slope is 1? Because it's 4 over 4 which simplifies to 1. Would you agree or disagree?
Anyone still here?
No worries. Take your time, I just wanted to make sure I wasn't alone haha
Let me get to the PC so I can use the draw. Easier for me than this Ipad
That's fine! Thank you
look at your graph
find 2 point (x1, y1) and (x2, y2)
plug into the formula and compute m
take a sec to look at this it has a lot but follow the colors. let me know if you still have
any questions about the slope before we continue
Okay cool, I figured out how to write it in slope format. basically it's y = m(slope)x + b (y-intercept) ? Was my original y-intercept right ? And this case it'd just be y = x + y-intercept because it's 0, am I right?
Ohhh!!! I had it literally backwards. Do you mind if I save these pictures so I can use them in the future if I need help with problems like this?
not very neat but yes you can keep!
notice my first response
the independent variable is the time spent practicing, the controlled variable, the input, x
the number of games won changes. it depends on the amount of practice
notice the points I used are the ones actually on the line--best fit
for these remember the variable you control is your x and what is dependent is your y
b is the y-value when x = 0.
Haha, I'm literally saving all of this. You've honestly helped so much
