Work Step by Step
In a plane, we define a rectangular coordinate system by drawing two perpendicular number lines, intersecting at their respective zeros.
The horizontal number line is called the x-axis, and the vertical is the y-axis.
The intersection of the axes is called the origin.
An ordered pair corresponds to each point in the plane, with the first coordinate taken from the x-axis, and the second from the y-axis.

Plotting $(\displaystyle \frac{7}{2},\frac{5}{2})$,
we start at the origin,
move $3.5$ units to the right,
and then $2.5$ units upwards.
The point is in quadrant I
