The slope between the points (4/5, 14/3) and (17/5, 8/3) is equal to -30/13.
In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;
Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope (m) = rise/run

By substituting the given data points (4/5, 14/3) and (17/5, 8/3) into the formula for the slope of a line, we have the following;

Slope (m) = (8/3 - 14/3)/(17/5 - 4/5)
Slope (m) = (-6/3)/(13/5)
Slope (m) = -2/(13/5)
Slope (m) = -30/13
