Answer:
Alison wins against Kevin by 0.93 s
Step-by-step explanation:
Alison covers the last 1/4 of the distance in 3 seconds, at a constant acceleration 
, we have the following equation of motion
where s (m) is the total distance, ta = 3 s is the time
Similarly, Kevin overs the last 1/3 of the distance in 4 seconds, at a constant acceleration 
, we have the following equation of motion:
tk = 4 s is the time
Since we can conclude that 
, so Alison would win.
The time it takes for Alison to cover the entire track
The time it takes for Kevin to cover the entire track
So Alison wins against Kevin by 6.93 - 6 = 0.93 s
Answer:
E: L is perpendicular to a line with slope 
.
Lines are perpendicular if the negative reciprocal of the slope is equal. For example, the reciprocal of 
is 
(remember, to get the reciprocal, simply switch the numerator and the denominator).
So, the negative reciprocal of is . This represents the slope of a line that is perpendicular.
Y-intercept: 3
x-intercept: 2
put (0,3) and (2,0) as points on the graph
