Answer:
y=2x-4
Step-by-step explanation:
To find an equation perpendicular to another one, you must find the negative inverse of the slope.
In this case, -1/2 has an inverse of -2, but because we're finding the negative inverse, the two negatives cancel out and we get 2, the slope of our perpendicular equation, which crosses the initial equation, making a right angle.

Step-by-step explanation:
Radius of the circle
Center of the circle (h, k) = (1.3, - 3.5)
Equation of the circle in center radius form is given as:
Plugging the values of h, k and r in the above equation, we find:
This is the required equation of the circle.
Postulates cannot be proven. They are assumptions that are made. There is no proof for a postulate. Postulates are used without proof.
