The steps for determining the center and radius of a circle using the completing the square method are shown below:
Fudgin [204]
The answer is option c.
 That is, the wrong step in step 6. It was written that the center of the circunference is the point (2.1). However, the general equation of a circumference is:
 (X- (a)) ^ 2 + (Y- (b)) ^ 2 = r ^ 2
 Where the point (a, b) is the center of the circle.
 So for this case the point for the center is: (-2, -1)

A line is passing through (7,-3) and it’s slope is -1/2, white the equation in point slope form
Crank

Equation of the line in point slope form is y + 3 = -1/2(x - 7)

Step-by-step explanation:

  • Step 1: Given slope of the line is -1/2 and passes through the point (x1, y1) = (7, -3). Equation in point slope form is y - y1 = m(x - x1)

⇒ y - (-3) = -1/2(x - 7)

⇒ y + 3 = -1/2(x - 7)
