Find the slope of a line parallel to a line that contains the points (9, -3) and (-3, 8).

Explanation:

Given the following points;

Points on the x-axis (x1, x2) = (9, -3)

Points on the y-axis (y1, y2) = (-3, 8)

To find the slope of a line parallel to a line;

Mathematically, the slope of a line is given by the formula;

Substituting into the formula, we have;

Therefore, the slope of the parallel line is -11/12.
