Find the distance cd rounded to the nearest tenth. C = (7,-4) d = (-7,-5)

The equation for distance is the sqrt of (x-x) ^2 + (y-y) ^2.

C (7,-4) D (-7,-5) 7 becomes x1 and - 4 becomes y1. - 7 is now x2 and - 5 is y2. Plug them in, the order doesn't matter.

(-7-7) ^2 + (-5+4) ^2

(-14) ^2 + (-1) ^2

196+1

sqrt of 197

or

Rad 197
