The average cost of tuition and fees at private fouryear colleges was $16,200, and in 2005 it was $20,100. Sketch a line that passes through the points (2000, 16200) and (2005, 20100).
My question is  find the slopeintercept form of the line in the sketch. What is the yintercept and does it have meaning in this situation?

Best ResponseYou've already chosen the best response.0First find the slope, which is the change in y (y2 minus u2) divided by the change in x. The slope intercept form is y = mx + b, so put the values of either coordinate into the formula with what you got for the slope for m, and solve for b. B is the y intercept. In this instance it means the tuition at the first year.

Best ResponseYou've already chosen the best response.0It is the tuition in the first year because the function is time as it relates to tuition, meaning time is x and tuition is y. Therefore when x equals zero, the y intercept is the tuition at the first year measured according to that data.

Best ResponseYou've already chosen the best response.0slope = change in tuition / change in years dont use 2000 and 2005, use 0 and 5 for your x values

Best ResponseYou've already chosen the best response.0Yeah sorry, I meant zero in the first post but I put it in the second one. You set x equal to zero.
