There are 5280 feet in a mile.
0, I put y=(0-7)x into a graphing calculator
The slope for the first one would be:
y2-y1/x2-x1, so replace those with the coordinates and you'll get:
-3-1/-7-(-7) => -4/0 so I guess the slope is zero
the slope for the second one would be:
-3-(-3)/5-(-4)=> 0/9 I think this one would be undefined.
Check to make sure, though!
LCD would be 18
8/9 = 16/18
2/3 = 12/18
1/9 = 2/18
