Question

A red and a blue dot are drawn on the given cartesian plane. Select the option that represents their coordinates.

• A. Blue dot (2, 5), red dot (-3, 1)
• B. Red dot (2, 5), blue dot (-3, 1)
• C. Red dot (5, 2), blue dot (1, -3)
• D. Blue dot (5, 2), red dot (1, -3)

Answer 1

The correct option is B Red dot (2, 5), blue dot (-3, 1)

Read the direction guidelines.



Distance of the red dot from the y-axis in the right direction toward the positive x-axis = 2 units
Distance of the red dot from the x-axis in upward direction = 5 units
So, coordinates of the red dot = (2, 5)

Distance of the blue dot from the y-axis in the left direction toward the negative x-axis = 3 units
Distance of the blue dot from the x-axis in upward direction = 1 units
Distance can never be negative, and the negative sign only represents the direction of the point from the axes.
So, coordinates of the blue dot = (-3, 1)
