Answer:
I can't see the pic
Step-by-step explanation:
To find the slope use the Rise over Run rule
It rises 2 units and runs 1 unit, so your slope is
2 or 2/1
To find the y-intercept just find where the line crosses the y-axis
it crosses at the -4 mark
Your slope is 2 and y-intercept is -4
Answer:

Step-by-step explanation:
To solve the question we refresh our knowledge of the quotient rule.
For a function f(x) express as a ratio of another functions u(x) and v(x) i.e
, the derivative is express as

from 
we assign u(x)=lnx and v(x)=x^2
and the derivatives
.
Note the expression used in determining the derivative of the logarithm function.it was obtain from the general expression of logarithm derivative i.e 
If we substitute values into the quotient expression we arrive at

Answer:
A = 27π units²
Step-by-step explanation:
Note that a central angle of 120 degrees corresponds to 1/3 of a full circle.
The area of the full circle is A = πr², or A = π(9 units)² = 81π units², and so
the area of the sector in question is 1/3 of that, or A = 27π units²
