-- As the line moves from left to right, it rises. So you know that
its slope is positive.
(All 4 choices have positive slopes, so that doesn't help.)
-- From the place where the line crosses the x-axis to the place
where it crosses the y-axis, it moves 2 units forward and also
rises 2 units. So you know that its slope is (2/2) = 1 .
(A. and C. both have slopes of 2, so it can't be either of those.)
(B.and D. both have slopes of 1,so it could be either of those.)
-- The line does not go through the origin. So you know that
its y-intercept is not zero.
(A. has no y-intercept, so that can't be it.)
-- The line crosses the y-axis at y=2, so you know that its y-intercept is 2 .
(B. has y-intercept of -2, so that can't be it.)
(C. and D. both have y-intercept of 2, so it's one of those.)
(But the slope has to be 1, and C. has slope of 2.)
(So it must be D.)

There are two possibilities, and we don't know which situation is true.
#1). School is in the middle, between home and grandparents.
Home --------- 3/8 ----------- School --------- 2/8 ------- Grandparents .
If this is true, then in the whole day, Tasha walks
(3/8 + 2/8 + 2/8 + 3/8) = 10/8 = 1.25 miles .
===========================================
#2): Grandparents house is in the middle, between home and school.
Tasha passes by them on her way to school, and stops there to visit
on her way back home.
Home ------- 1/8 ------- Grandparents ---------- 2/8 ---------- School
If this is true, then in the whole day, Tasha walks
(3/8 + 2/8 + 1/8) = 6/8 = 3/4 mile .
