Could someone explain to me how to solve this question?

write the equation of the line, in point-slope form. identify the point (-2, -2) as (x1, y1).

Step-by-step explanation:

A line is written in the point-slope form if its equation is in the form

where

is the slope of the line, calculated using the two points and

In this problem, we have the following two points:

Therefore we can calculate the slope of the line:

And so, the equation of the line in point-slope form is

b) well because you get well
