Slope = change in y ÷ change in x = (7 − 5) ÷ (7 − 3) = 2 ÷ 4 = 1/2. 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 1/2, which matches the calculation or reasoning shown.
