A)horizontal intercept of the line to the origin divided by the distance from the origin to the vertical intercept of the line.
B)origin to the horizontal intercept of the line minus the distance from the origin to the vertical intercept of the line.
C)vertical intercept of the line to the origin divided by the distance from the origin to the horizontal intercept of the line.
D)vertical intercept of the line to the origin minus the distance from the origin to the horizontal intercept of the line.

The slope of a line is defined as the ratio of the vertical change to the horizontal change between any two points on the line. In this case, we can calculate the slope of the downward-sloping straight line by taking the vertical distance from the vertical intercept to the origin, and dividing it by the horizontal distance from the origin to the horizontal intercept. This is equivalent to choice C. The other choices do not give the correct formula for calculating the slope.
