If the equal is 55x + 35y = 200
x: time-driven at 55 miles/hour
y: time-driven at 35 miles/hour
If the car spends 2.5 hours at 35 miles per hour, then it drove:
55x + 35(2.5) = 200
55x =35
y = 112.5
There the drive spent about 2.5-hour driving at 55 mph.

So for this one, all your going to do is divide 3.37 by -8 so x becomes isolated
-8/3.37
x= -2.37 (Rounded to the nearest tenth)
Answer: 1/3
Step-by-step explanation: slope is the difference between the y values over the difference of the x values
