The scale of a map is 2 cm : 21 km. find the actual distance for 9 cm, 12.5 cm, 14 mm, 3.6 m, 4.5 cm, and 7.1 cm.

Asegment in the complex plane has a midpoint at 7 – 2i. if the segment has an endpoint at 11 – 3i, what is the other endpoint?

Write the function for the graph. (1.8) (0,4)

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
