Answer:
C. 279.3
Step-by-step explanation:
To find the mean of a set of numbers you have to add all of them together and divide them by how manys numbers there are
If we add all the numbers together it equals 2514
There are 9 numbers here
2514/9=279,333333
Therefore, the answer is C

Answer:
Option C) y = -2x - 6
Step-by-step explanation:
<u><em>The correct question is</em></u>
In the xy coordinate plane the slope of line p is 1/2 and its x-intercept is -3. Find the equation of a line that is perpendicular to p and intersects p at is x-intercept.
step 1
Find the slope of a line that is perpendicular to p
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)

we have
----> slope of line p
substitute

----> slope of the line perpendicular to p
step 2
Find the equation of the line that is perpendicular to p and intersects p at is x-intercept
we have


Find the equation of the line in point slope form

substitute


First,multiply the -2 by everything in the brackets
so that's, -6x-(b-4x)+(x+6b)
then combine like terms
that's -6x-(7b-3x) which is
-3x-7b I believe
