1) (-1 1/4, 3/4)
Step-by-step explanation:
Coordinates in two dimensions are given as an ordered pair, (x, y). That is, the x-coordinate is always listed first, followed by the y-coordinate.
The x-coordinate is the distance to the right of the x=0 point, or y-axis. Distances to the left have a negative sign. Here, the given point is 5 grid squares to the left of the y-axis, so has an x-coordinate of -5/4 = -1 1/4. (Each grid square on this graph is 1/4 unit.)
The y-coordinate is the distance above the y=0 point, or x-axis. Distances below have a negative sign. Here, the given point is 3 grid squares above the x-axis, so has a y-coordinate of 3/4.
The coordinates of the given point are (x, y) = (-1 1/4, 3/4).

Additional comment
The above discussion refers to coordinates on the "Cartesian plane." There are other ways of determining location. Some are based on the distance from an origin and an angle from a reference direction. Then, the ordered pair is not (distance right, distance up), but may be (distance from origin, CCW angle from 'right'). In navigation, it may be (latitude angle, longitude angle), or (bearing distance, bearing angle CW from North).
