In distance formula, what if, x1, x2, y1, y2 take negative values? Class 9

In distance formula, what if, x₁, x₂, y₁, y₂ take negative values? Class 9

Question 1.

In distance formula, what if, x₁, x₂, y₁, y_2 take negative values? Class 9

Answer:

If the coordinates are negative, the distance formula remains the same, and the distance is positive, since after squaring, the values become positive.

Question 2.

In the given figure, triangle AMD is reflected in the y-axis. What are the coordinates of the images of points A, M, and D? Class 9

Answer:

The coordinates of the images of points A, M and D are (-3, 4), (-9, 6) and (-7,1) respectively.
