A. $$\frac{1}{2}$$
B. $$1$$
C. $$3$$
D. $$4.5$$
E. $$9$$

Official Solution:

The distance from the Y-axis to point K is $$\frac{1}{3}$$ of the distance from the X-axis to point K. If the coordinates of K are (-3, y), what is the distance between point K and X-axis?

A. $$\frac{1}{2}$$
B. $$1$$
C. $$3$$
D. $$4.5$$
E. $$9$$

Point K has the coordinates (-3, y) means that it's somewhere on the line $$x=-3$$. Hence the distance from this point to the Y-axis is 3 units.

Since the distance from the Y-axis to point K is $$\frac{1}{3}$$ of the distance from the X-axis to point K, then the distance from K to the X-axis is 9 units.

brunel : By inferring the point is on the line x = -3, how were you able to determine the distance from y axis is 3 units ?

x = -3 is a line parallel to y-axis. Any point on x = -3 is 3 units apart from y -axis.

Hope it's clear.

Hi Bunuel.... although its not there in the answer...... can it be -9 ?

Bunuel could you please explain below ask:
distance from the Y-axis to point K is 1313 of the distance from the X-axis to point K, then the distance from K to the X-axis is 9 units.How we get 9 units from there?

Distance is always absolute value so cant be negative

Brilliant solution. I was calculating distance between 2 points, and solving for y.

I think this is a high-quality question and I agree with explanation. It would be a nice trap to add -9 as an answer.
