Answer:
x = 1/2
Step-by-step explanation:
We can solve the equation of the unit circle for x, then fill in the given value for y and evaluate.
x^2 +y^2 = 1
x^2 = 1 -y^2
x = √(1 -y^2)
Using y = (√3)/2, we get ...
x = √(1 -((√3)/2)^2) = √(1 -3/4) = √(1/4)
x = 1/2

y - y₁ = m(x - x₁)
y - 5 = -3(x - (-2))
y - 5 = -3(x + 2)
y - 5 = -3(x) - 3(2)
y - 5 = -3x - 6
+ 5 + 5
y = -3x - 1
