Circle Center Formula: (x - h)² + (y - k)² = r²
- <em>(h, k)</em> is center
- <em>r</em> is radius
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>(h, k)</em> = (-2, 1)
<em>r</em> = 5
<u>Step 2: Find Equation</u>
- Substitute in variables [Circle Center Formula]: (x - -2)² + (y - 1)² = 5²
- Simplify: (x + 2)² + (y - 1)² = 25

Answer:
<em>B) -7x + 7y = -49</em>
Step-by-step explanation:
This is a y=x plot/line shifted by 7 units.
This can also be verified plugging in the values of x=0,y=-7 and x=7,y=0. The only equation which satisfies these points in Equation B. These points have been chosen as they're the intercepts of this plot.

Answer:
y=6x-10
Step-by-step explanation:
Use Point-Slope form to solve this problem
Point Slope Form: y-y1=m(x-x1)
M is your slope, in this case, m will be 6
Plug in the values of your coordinates (3,8), ambigously, 3 will be the value of x1 and 8 will be the value of y1.
New equation: y-8=6(x-3), start solving from here
y-8=6x-18
Use inverse operations to get y alone, opposite of subtraction is additiin so add 8 to both sides of the equation
y=6x-10
