What is the equation of a line, in point- slope form, that passes through (5, −3) and has a slope of (2/3) ?

Point slop form is y-y1=m(x-x1)
Therefore the answer would be y-3=2/3(x-5)

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.
