Find the distance CA:
The distance between two points (x₁,y₁),(x₂,y₂) = d
[tex]d = \sqrt{ (x2-x1)^{2} + (y2-y1)^{2} } [/tex]
The coordinates of point C = (-2,2)
The coordinates of point A = (0,0)
The distance CA distance between C and A
∴The distance CA = [tex]\sqrt{ (-2-0)^{2} + (2-0)^{2} } [/tex] = 2√2
