# Determine the coordinates of the points shown. Tell in which quadrant each point lies. Assume the coordinates are integers.

The coordinates of the point shown are (3,4) and it lies in quadrant I.

See the step by step solution

## Step 1. Given information.

The given graph is:

## Step 2. Determine the coordinates.

First note that the scale of x-axis is 1 and the scale of y-axis is 2.

The point shown is 3 tick units to the right on the horizontal axis (scale = 1) and 2 tick up on the vertical axis (scale = 2).

The point lies in quadrant I, it means both coordinates are positive. So, the required coordinates are (3,4).

## Step 3. Conclusion.

The coordinates of the point shown are (3,4) and it lies in quadrant I.
