Lesson 4.2:
*FYI...if we have any point and the slope...we can write the
equation of the line by "plugging them into the slope­intercept
form and finding the y­intercept!
Ex­­>the line goes through (2,1) and has a slope of 3:

*FYI #2...if we have any 2 points...we can also write the equation
for the line!
Ex­­>the line goes through (3, 1) and (2, 4)
