Answer 1

are you having trouble with this question? the source you've provided explains simple linear regression, albeit in a very thorough way. I can try to explain it in more simple terms, if you'd like.

Answer 2

in statistics, the general definition of regression (also called regression analysis) is a statistical method used to quantify the relationship between two variables. for simple linear regression, the relationship between two variables is said to be linear, meaning that a graph of the data should roughly resemble a straight line.

the source you listed gives the formula

y = β0 + β1x + ε

if β1 is a real # coefficient, and β0 then the y = β0 + β1x part resembles the linear equation y = mx + b, where m is the slope and b is the y-intercept. ε is an error term, which is another constant.

you can input a data set into statistical software, and it will calculate the simple regression line (there's a lot of math involved, which you may or may not need to know) that will approximate the data.

does that make it a little more clear? please let me know if you'd like me to simplify it further
