Answer:
y - 1 = 0
Step-by-step explanation:
We know that Equation of a line is given by,
y - y₁ / x - x₁ = y₂ - y₁ / x₂ - x₁
Let A(-2,1) and B(2,1)
x₁ = -2 ; x₂ = 2 ; y₁ = 1 ; y₂ = 1
Substituting the values,
y - 1 / x - (-2) = 1 - 1 / 2 - (-2)
y - 1 / x + 2 = 0
y - 1 = 0
c=PI*d
divide both sides by PI to get d by itself
d = c/PI
