OA (2.0), (0, 2), and (-1,-3)
OB. (0, 2), (2.0), and (1,-1)
OC (1, 1), (2.0), and (-1,-3)
.D. (1,1),(0, 2), and (-1,-3)
Of (2.0), (1, -1), and (-1,-3)

(1,1); (2,0) and (-1,-3)

Step-by-step explanation:

Given

---- (1)

--- (2)

---- (3)

Required

The vertices of the triangle

To do this, we simply equate the equations.

Equate (1) and (2)

Collect like terms

Divide by -3

Substitute in (1), to get the y-coordinates

So, the coordinate is: (1,1)

Equate (1) and (3)

Collect like terms

Divide by -2

Substitute in (1) to get the y coordinate

So, the coordinate is (2,0)

Equate (2) and (3)

Collect like terms

Substitute in (2) to get the y coordinates

So, the coordinate is (-1,-3)
