Statistical Inference is... Select one or more:
a. sampling error
b. using sample data to make decisions about the larger population
c. the likelihood of sample results as or more extreme than those observed
d. the method for determining when the null hypothesis is true

Slope intercpet form is y = mx + b

1:

y = 0.5x + 34

It is 34 so our b aka y-intercept is 34, and it is rising by 0.5 so our m is 0.5

2:

y = x + 40

A movie is 1 dollar so 1x = x and the pass is 40 so our b aka y-intercept is 40

3:

y = 5x + 3

Every hour is 5 (x=hour) plus a flat fee of 3 so our b aka y-intercept is 3

(there is some repeating in what I am saying [our b aka y-intercept is blah blah] as these are all similar equation processes so sorry about that, hope this helps! )
