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 yintercept 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 slopeintercept form and use it to predict the number of games that could be won after 13 months of practice. (5 points)

Best ResponseYou've already chosen the best response.0For part A I have the yintercept as 1 and it represents the number of games won. I just need help with part B :)

Best ResponseYou've already chosen the best response.0I'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

Best ResponseYou've already chosen the best response.0@triciaal I think the slope is 1? Because it's 4 over 4 which simplifies to 1. Would you agree or disagree?

Best ResponseYou've already chosen the best response.1look at your graph find 2 point (x1, y1) and (x2, y2) plug into the formula and compute m

Best ResponseYou've already chosen the best response.1take 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

Best ResponseYou've already chosen the best response.0Okay cool, I figured out how to write it in slope format. basically it's y = m(slope)x + b (yintercept) ? Was my original yintercept right ? And this case it'd just be y = x + yintercept because it's 0, am I right?

Best ResponseYou've already chosen the best response.0Ohhh!!! 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?

Best ResponseYou've already chosen the best response.1not 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

Best ResponseYou've already chosen the best response.1notice the points I used are the ones actually on the linebest fit

Best ResponseYou've already chosen the best response.1for these remember the variable you control is your x and what is dependent is your y b is the yvalue when x = 0.
