Answer 3

@CoreyContini Do you know when slope of a line is undefined?

Answer 4

Slope of a line is defined as the change in y over change in x. If a line passes through two points (x2, y2) and (x1, y1) then its slope (m ) is given as
\[m=\frac{y2-y1}{x2-x1}\]
It's also defined as
\[m=\frac{\Delta y}{\Delta x}\]

Answer 5

here
\[\Delta y= \text{Change in y}\]
\[\Delta x= \text{Change in x}\]
