What are the coordinates of the center and the radius of the circle with equation: (x - 4) 2 + (y - 3) 2 = 25 ?

Center (-4,-3) Radius = 25 units

Center (-4,-3) Radius = 5 units

What does (h,k) standard for in the standard circle equation?

(h,k) is the center of the circle

(h,k) is a point on the circle.

(h,k) is a point that we guess and find

(h,k) is the radius of the circle

What does the r in the standard equation stand for?

r is the diameter of the circle

r is the x coordinate of the center of the circle

r is the y coordinate of the center of the circle

What is the center and radius of a circle with an equation (x+5) 2 + (y-1) 2 = 64

Center is (-5, 1) and radius is 8

Center is (5,-1) and radius is 8

Center is (-1, 5) and radius is 8

Center is (-5,1) and radius is 64

What are the coordinates of the center and the radius of the circle with equation: (x - 4) 2 + (y - 3) 2 = 25 ?

Center (-4,-3) Radius = 25 units

Center (-4,-3) Radius = 5 units

Find the equation of the line that passes through the points (2, -6) and (0, -3)

y = − 3 2 x − 3 y=-\frac{3}{2}x-3 y = − 2 3 x − 3

y = 3 2 x + 3 y=\frac{3}{2}x+3 y = 2 3 x + 3

y = 2 3 x − 6 y=\frac{2}{3}x-6 y = 3 2 x − 6

y = − 3 2 x − 6 y=-\frac{3}{2}x-6 y = − 2 3 x − 6

Which equation below represents the steepest line?

y = 5 2 x + 3 y=\frac{5}{2}x+3 y = 2 5 x + 3

y = 3 2 x + 1 y=\frac{3}{2}x+1 y = 2 3 x + 1

y = 1 8 x − 5 y=\frac{1}{8}x-5 y = 8 1 x − 5

y = 9 4 x − 2 y=\frac{9}{4}x-2 y = 4 9 x − 2

What is the equation of the line graphed below?

y = − 3 4 x + 5 y=-\frac{3}{4}x+5 y = − 4 3 x + 5

y = 3 4 x + 5 y=\frac{3}{4}x+5 y = 4 3 x + 5

y = − 3 x + 5 y=-3x+5 y = − 3 x + 5

y = − 3 x + 4 y=-3x+4 y = − 3 x + 4
