12. Triangle ABC is shown on the coordinate plane. If it is translated 4 units to the left and 3 units up, what are the coordinates of the vertices of the image?

A. A (1.1), B'(6,0), C (1.4)
B. A'(-1,1), B'(0,6), C (-4,-1)
C. A' (1.-1), B'(6,0). C'(-4,1)
D. A'(-1,-1), B'(0.6), C'(4-1)

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.
