The answer should be the first one, SF = 1/2
A linear function is one whose formula can be written in the form
Ax + By = C where A, B, C are real numbers and A, B are not both 0. (This is standard form, too.)

"Cross multiply."

Subtract 12.

Subtract 2y.

This matches up with standard form with A = 3, B = -2, C = -20.
It's a linear function.

Answer:
EF = 13.1
FD = 35.3
Step-by-step explanation:
The distance between two points on a number line is the positive difference between their coordinates.
EF = F - E = 19 -5.9
EF = 13.1
__
FD = F - D = 19 -(-16.3) = 19 +16.3
FD = 35.3
