Since the point lies of the negative side of the x axis, it forms an angle of 180° with the positive direction of the x axis.
So, if we start from (1,0), a rotation of 180° will bring us to (-1,0). If we scale the point with factor 3, we have (-3,0).
So, the polar coordinates are (3, 180°)

Answer:
x = 2 and y = -2
Step-by-step explanation:
a) 5x-4y = 18
b) x+3y = -4
b) x = -3y - 4
a) 5 (-3y - 4) - 4y = 18 (substitution)
a) - 15y - 20 - 4y = 18
a) -19y = 18 + 20
a) y = 38/-19
y = -2
b) x + 3(-2) = -4
b) x - 6 = -4
x = 6-4 = 2
