Answer:
non-linear
Step-by-step explanation:
it is nonlinear because if the numbers go up and then down then its not a straight line. therefore its not linear.
The second one!!!!!!!!!!!
Answer:
move the decimal to the left twice
Step-by-step explanation:
Answer:
(x + 1)² + (y - 6)² = 50
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.
The radius is the distance from the centre to a point on the circle.
Calculate r using the distance formula
r = 
with (x₁, y₁ ) = (- 1, 6) and (x₂, y₂ ) = (- 6, 1)
r = 
= 
= 
= 
(h, k ) = (- 1, 6 ), then
(x - (- 1))² + (y - 6)² = (
)² , that is
(x + 1)² + (y - 6)² = 50 ← equation of circle
