B is the correct answer. A,C, and D will all give you the correct slope.
8:32 simplyfies to 1:4 .....there is your answer 1:4
If Mallory makes $42.50 per hour and she works 20 hours a week, we multiple those two and we get:
42.5 * 20 = 850
So she earns $850 per week.
Mallory saves half of that amount she would have $425 per week.
In 4 weeks she would have:
425 * 4 = 1700
Mallory will save $1,700 in four weeks.
