Answer:
y = 1 and y = - x -
Step-by-step explanation:
The points whose distance is 2 units from point with coordinates (2, -1) lie on circumference with center at (2, -1) and r = 2;
There are 2 lines/tangents which are passing point (-2, 1) and ⊥ to radius of circle (x - 2)² + (y + 1)² = 2²
Equation of the first line is y = 1
Equation of the second line is y = - x -
