Victor draws one side of equilateral ∆PQR on the coordinate plane at points P (–9, –2) and Q (–2, –2). What are the two possible coordinates of vertex R? Round to the nearest tenth.

Step-by-step explanation:

Given

The two vertices of a equilateral triangle are

Suppose the third vertex is

Side length in equilateral triangle are equal.

Similarly,

Subtract (i) and (ii)

Insert the value of in equation (ii)

So, two possible vertex are

look up a corrdinate plane and do what the thingy says and boom
