Answer
Quadrant III
.
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.
The axes divide the plane into 4 regions called quadrants, of which
we take the upper right to be quadrant I, and count the other three in the counterclockwise direction.

Plotting $(-3,-1)$,
we start at the origin,
move $3$ units to the left,
and then $1$ units downwards.
The point is in quadrant $III$ (the lower left quadrant)
