the answer is 7/24

Explanation:

always remember that slope formula is (y_2-y_1)/(x_2-x_1) so you can apply this with this equation

7/24

Explanation:

The slope of a line can be found using "rise"/"run", where "rise" is the difference of the y coordinates and "run" is the difference of the x coordinates.

The x coordinate from the first pair is -3, from the second ordered pair is 21. Therefore we have -3-21=-24 which was the "run".

The y coordinate from the first pair is 7, from the second ordered pair is 14. Therefore we have 7-14=-7 which was the "rise".

We know that the slope can be found using "rise"/"run" => (-7)/-24 => 7/24
