Step-by-step explanation:
The difference in coordinates from home to school is ...
school - home = (5, 0) - (-3, -4) = (8, 4)
The gas station is halfway between home and school, so is (8, 4)/2 = (4, 2) from home:
gas station = home + (4, 2) = (-3, -4) + (4, 2) = (1, -2)
Similarly, the fast-food restaurant is halfway between the gas station and home, so is (4, 2)/2 = (2, 1) from home:
fast-food = home + (2, 1) = (-3, -4) + (2, 1) = (-1, -3)
