Answer: Yes, you can tell how to model real life relationships. For example, a linear function is written at y=mx+b. Y is the total value, b is initial value, and m is the slope of the function.
Step-by-step explanation:
Real life example:
Your school needs to raise money. To do this, they host a school dance! The admission is $5 (initial cost, b), plus an additional $3 dollars for drinks. 3 would be the slope per drink, so this can be represented by y=3x+5!
Assuming the speed is in miles per hour, simply divide the total distance by time.
515.97/6.5
The answer is 79.38 miles per hour
