Answer:
yes no yes yes hi my name is robert
Step-by-step explanation:
Determine a relationship between the x- and y- values. write an equation.
x =1 2 3 4
y = 4 5 6 7Step One: Determine two coordinates written as (x,y)
(1,4) (2,5)
Step Two: Use the formula
Step Three: Simplify to identify the slope
Step Four: Plug your slope (m) into the equation y=mx+b
y = 1x + b
Step Five: Using a coordinate of your choice, plug x and y in to their respective places. (I'm using (1,4))
4 = 1*1 + b
Step Six: Simplify
Step Seven: Isolate b
Step Eight: Rewrite your equation
y = 1x + 3
OR
y = x + 3
(It's more likely you'll see it written the second way)

Answer:
D
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 6, - 8), thus
(x + 6)² + (y + 8)² = r²
The radius is the distance from the centre to a point on the circle
Calculate r using the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 6, - 8) and (x₂, y₂ ) = (0, 0)
r = = = = 10
Hence
(x + 6)² + (y + 8)² = 100 → D
