Slope = change in y ÷ change in x = (-1 − -6) ÷ (-4 − -6) = 5 ÷ 2 = 5/2. Here, slope tells how much y changes for each 1-unit change in x. A negative slope means the line goes downward from left to right, while a positive slope means it goes upward. Always subtract the coordinates in the same order for y and x so the sign of the slope stays correct. The correct answer is 5/2, which matches the calculation or reasoning shown.
