What is the equation of a circle with radius 4 and center (0, 8)?

• x² + (y-8)² = 16

• (x-8)² + y² = 4

• x² + (y-8)² = 4

• x² + (y+8)² = 16

Which equation is written in STANDARD form?

• y = 1/2x + 2

• y - 3 = -5(x + 2)

• 7x + 2y = 9

• 3x + 2 = y

For an equation written in standard form Ax + By = C, which of these are TRUE?

• y intercept is when x = 0 so plug 0 in for x and solve for y to get the coordinates of the  y intercept  (0,y)

• x intercept is when y = 0 so plug 0 in for y and solve for x to get the coordinates of the  y intercept  (x,0)
