The simplified fraction is 62/7
The correct answer is A.
The independent variable is time and the dependent variable is distance; this means the slope tells us how far she goes per minute. Since the slope is negative and we are referring to her distance from her house, this means the distance from her house is decreasing, which means she is getting closer to her house.
The angles are congruent and corresponding. You can find the missing angles by subtracting the existing ones from 180.
