x² + y² – 10x + 6y + 18 = 0 x² – 10x + y² + 6y + 18 = 0 x² – 10x + 25 - 25 + y² + 6y + 9 - 9 + 18 = 0 (x-5)² + (y+3)² -16 = 0 (x-5)² + (y+3)² = 16 (x-5)² + (y+3)² = 4² Center at (5,-3) radius = 4 Part 2 1. Complete the square for x and y 2. Put in the format for a circle. (x-h)² + (y-k)² = r², center at (h,k) with radius = r

I need with these problems

ch4aika [34]

Answer:

1. $\frac{5}{6}$

3. $\frac{7}{0}$ (undefined slope)

5. $-\frac{7}{4}$

7. $24$

Step-by-step explanation:

slope (m)

rate of change (r)

1. m = $\frac{y_2-y_1}{x_2-x_1}=\frac{8-3}{13-7} =\frac{5}{6}$

3. m = $\frac{y_2-y_1}{x_2-x_1}=\frac{4-(-3)}{9-9} =\frac{7}{0}$ (undefined slope)

5. m = $\frac{y_2-y_1}{x_2-x_1}=\frac{-1-6}{0-(-4)} =\frac{-7}{4}=-\frac{7}{4}$

7. r = $\frac{f(b)-f(a)}{b-a}=\frac{24-0}{1-0}=\frac{24}{1}=24$

Hope this helps!
