Arectangle on a coordinate plane is translated 5 units up and 3 units to the left. which rule describes the translation?
a) (x, y) → (x + 5, y – 3)
b) (x, y) → (x + 5, y + 3)
c) (x, y) → (x – 3, y + 5)
d) (x, y) → (x + 3, y + 5)

Any time you move up or down, it affects the y coordinate and going up is positive so 5 units up is y + 5.
Moving left or right affects the x coordinate and moving left is negative so x - 3

(x - 3, y + 5)

So the answer is Option C).

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.
