Answer:
y=-3x-8
Step-by-step explanation:
y=1/3x+9
slope is 1/3
perpendicular slope = m
(m)(1/3) = -1
m = -3
Point slope form
(y+2)/(x+2)=-3
y+2=-3x-6
y=-3x-8
Answer:

Step-by-step explanation:
step 1
Find the radius of the circle
we know that
The circumference of a circle is equal to

we have


substitute the values



step 2
Find the area of the circle
The area of the circle is equal to

substitute the values


Y-INTERCEPT

The y-intercept is where the equation/curve/parabola cosses the y-axis.
The y-axis is where x = 0. (The x-axis is where y = 0)
To find the y-intercept:

The y-intercept must be at (0, 10)
X-INTERCEPT (ROOTS/SOLUTIONS)

We need to use the quadratic formula
The quadratic formula helps us find what values of
make the equation = 0
Quadratic formula: 

The x-intercepts are at:

1/5 is greater because it equals 0.2
0.2 has an imaginary 0 at the end, to make it 0.20
.20 > 0.15
Therefore, 1/5 is greater than 0.15
