Answer:
(a) (-3/4, 1/2)
Step-by-step explanation:
There are 4 grid lines between 0 and 1 in each direction, so each grid line represents 1/4 unit. Two of them is 1/2 unit; 3 of them is 3/4 unit. The x-dimension is listed first in the ordered pair.
Point S has coordinates (-3/4, 1/2).
I like to reduce everything by half if I don't already know the answer.
It just so happens that is the reduced fraction.
All I did was halve 18, which is 9, and halve 34, which is 17.
