Line ab contains points a (3, −2) and b (1, 8). the slope of line ab is −5 negative 1 over 5 1 over 5 5

-5

Step-by-step explanation:

The slope of a line passing through (a,b) and (c,d) is given by :-

Then the slope of the line AB contains points A (3, −2) and B (1, 8) will be :-

Hence, the slope of the line AB contains points A (3, −2) and B (1, 8) = -5
