Best ResponseYou've already chosen the best response.1yintercept is where the line crosses the yaxis (the vertical axis) any idea where the line crosses the yaxis?

Best ResponseYou've already chosen the best response.1yes. so 3 matches after how much practice ?

phi

Best ResponseYou've already chosen the best response.1so that is the answer to part A (if you make that into a coherent thought)

Best ResponseYou've already chosen the best response.1if they don't practice, we expect them to win only about 3 matches.

Best ResponseYou've already chosen the best response.1for part B you want y = mx + b we need m and b from part A we know b to find m (the slope) look at x=4 (get its y value) and at x= 7 (ditto) what two points do you read off the line?

phi

Best ResponseYou've already chosen the best response.1ok, those are the y values. you want to write the two points as (4,10) and (7,16) now find the slope which is change in y divided by change in x can you do that ?

Best ResponseYou've already chosen the best response.1in other words, what is 16 10 ?

phi

Best ResponseYou've already chosen the best response.1remember y is the 2nd number in each pair (or the height of the point above the xaxis) change in x is 74 = 3 so the slope is 6/3 = 2 ok?

Best ResponseYou've already chosen the best response.0ok that makes sense. sorry if I seemed dumb there I just didn't remember that y is the second number in each pair

Best ResponseYou've already chosen the best response.1the last part is to "put in" 13 for x in the equation and then calculate y

phi

Best ResponseYou've already chosen the best response.1did you do y = 2*13+3 ? for the last part. you get 29 matches

Best ResponseYou've already chosen the best response.0yes I did do that. thank you soooo much @phi i really appreciate it..

Best ResponseYou've already chosen the best response.1for part B, they ask what the number of matches you will win if you practice 13 months that is why we use x=13
