The slope, m, of the line is calculated through the equation,
m = (y₂ - y₁) / (x₂ - x₁)
where x's are the abscissas of the ordered pair and x's are the ordinates. Substituting the given values to the equation above,
m = (0 - 3)/(5 - 1) = -3/4
The slope of the line is -3/4 and the answer is letter B.
