The graph shows a linear relation between variable y and x. Consider two quantities p and q defined by the equations.
`p=y/x`
`q=(y-b)/x`

As x changes from zero to a, which of the following statements are correct according to the graph?

Options

A. Quantity p increases and q decrease.
B. Quantity p decrease and q increases
C. Quantity p decreases and q remain constant
D. Quantity p increases and q remain constant.

Answer

C

Explanation

q is slope of given line, which is a constant for a straight line.
p is slope of the line joing origin and point on the kine, which decreases as x increases.
