What Quadrant does point (7, -4) belong to?

• 3

• 4

• 1

Find the center and radius:

y² + 2x + x² = 24y - 120

• c = (1, 144) r =25

• c = (-1, 12) r =5

• c = (1, -12) r =5

What Quadrant does the center of this circle belong to?

(x + 2)² + (x + 4)² = 16

• 1

• 2

• 3

What do you call the vertical axis of the Cartesian plane?

Solve for the midpoint:

(14, -2) and (7, -8)

• (10.5, -5)

• (6, -0.5)

• (3.5, -3)

Choose the x-intercept form the following choices.

• (0, 6)

• (-3, 9)

• (2, 0)

Find the coordinates of the equation:

(x² - 3) + (y² + 4) = 13

• (3, -4)

• (-4, 3)

• (-3, 4)

It is a line that passes through the x-axis.

Transform the general equation:

x² + y² - 4x + 6y - 2 = 0

• (x² + 2) + (y² - 3) = √15

• (x² - 2) + (y² + 3) = √15

• (x² + 3) + (y² - 2) = √15

The distance formula is derived from the _____.
