Select the equation below that is parallel to the line with the equation y = 3x + 2 and goes through the point (3,6).
y - 3x - 3
y = -1/3x+5
y=-1/3x - 7
y - 3x - 9

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.
