KYOTE Day 1
A. I can solve rate problems
Example:
1. An east bound car is going 6 miles per hour faster than a westbound car. The cars are 408
miles apart 3 hours after passing each other on a highway. What is the speed, in miles per
hour, of the east bound car?
2. If a man walks at the rate of 3 feet per second, how any minutes will it take him to walk
3720 feet?

E. I can determine the x and y intercepts of a linear equation.
Example:
6. The graph of the line with equation y = 3x + 5 crosses the x-axis when x = ?
7. The graph of the line with equations 2x + 3y = 10 crosses the y-axis when y = ?
