Answer:
5x - 4y = 20
Step-by-step explanation:
First find slope
(5- -10)/(8- -4) = 15/12 = 5/4
(y - 5) = 5/4 (x - 8), multiply everything by 4 so you don't have fractions
4y - 20 = 5x - 40
5x - 4y = 20
1. 1 hour is 3x20 minutes so distance is 3 km wi=hich is 3000 metres
2. same way as before but now 4x 1km is 4000 metres, minus the previous answer is 1000 metres.
3. 26 days x 24 hours (in one day) = 624 hours
4. A) 1 hour 45 minutes
B) 10:10, because add one hour and then minus 10 minutes (probably easiest way)
I think 53.088 is the answer
