1/2. It isn't asking for another solution, just the fraction.
Hope this helps!
The number of variables in the problem is 3
Answer: 100
Step-by-step explanation:

3 x 25 = 75
4 x 25 = 100
Depends on MPH or Miles Per Hour.
Going 10 mph = 30 minutes
Going 50 mph = 10 minutes
Etc.
Point slope form is y-(-4) = 1/2(x-(-2)
y+4 =1/2 (x+2)
now the standard form 2y+8=x+2
so -x+2y=-6 is the equation for line p in standard form
