ap stats chapter 12 phrasing

slope

for every 1 unit increase in x, the predicted y will increase/decrease by b

y-int

with no x, the y would increase/decrease by

s

when using the least squares regression line where x= and y=, we will typically be off by s units

SE

if we repeated this experiment many times, the sample slope will typically vary about SE from the true slope of the line

r²

about r² % of the variation in y will be accounted for by the linear model relating x to y
