Problema Solution
After driving for 2 hours you are at mile market of 262 after 5 hours you reach a mile market 448.
Write the linear function modeling your trip. Use y=mx+b form. When x= hours traveled and y= miles traveled
Answer provided by our tutors
y = mx + b
After driving for 2 hours you are at mile market of 262:
y = 262, x = 2
2m + b = 262
After 5 hours you reach a mile market 448:
y = 448, x = 5
5m + b = 448
We have the following system of equations:
2m + b = 262
5m + b = 448

........
m = 62
b = 138
The linear function modeling the trip is y = 62x + 138.
