The simplest form would be -3/4
None of those are correct. x= 8 and 2/3
The line crosses the x-axis at (0,4). The slope is also -1.
The cheetah is running initially at 27.5 because 70 - 42.5 = 27.5 mph
Dividing by 5 is equivalent to dividing by 10 and then multiplying by 2.
therefore:
63.5/5 = (63.5/10) * 2 = 6.35 * 2 =12.70 which rounds to 13.
