2. 
would be the second y-value (in the second ordered pair), 2, and 
would be the first y-value (in the first ordered pair), also 2.
3. Same for the x-values. 
is -2 and 
is 4

Answer:
D. 80 mph
Step-by-step explanation:
d- distance
- d/50= 0.6d/40+0.4d/x
- 1/50= 0.3/20+0.4/x
- 0.4/x= 0.02- 0.015
- x= 0.4/0.005
- x= 80 mph
