Which of the sets of ordered pairs represents a function? p = {(6, –7), (3, –2), (–9, 2), (–5, –7)} q = {(–7, 8), (4, –6), (–3, 1), (1, 5)} (1 point) only p only q both p and q neither p nor q

Both P and Q are  functions.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
