a number to be divided by another number
Answer:
0.28571 miles (keystrokes)
The slope would be y = -1/2x + 3
The y intercept is where the line crosses the y axis which is at 3 and the slope is rise over run -2/4 or -1/2
It's easier to write if you convert 1/4 into 0.25.

Then you use algebra to find that he ran the mile in 6.4 minutes.
