Answer 2

Since you are given a table, to calculate the slope you will need to use the following formula

\(\sf\Large Slope = \frac{\color{blue}{y_2}-\color{red}{y_1}}{\color{green}{x_2}-\color{purple}{x_1}}\)

Where the two points are in the form:

\(\sf\Large (\color{purple}{x_1},\color{red}{y_1})~and~(\color{green}{x_2},\color{blue}{y_2})\)

Answer 3

Or you can graph out all the points and use this to determine whether you have a positive, negative, zero, or undefined slope
