Answer:

Step-by-step explanation:

The equation of the nth term of the arithmetic sequence is: $a_n =a_1+d(n-1)$

d = 9 - 4 = 5

a₁ = -6

Therefore:

$a_n =-6+5(n-1)\\\\a_n =-6+5n-5\\\\a_n =5n-11$

Answer:

Step-by-step explanation:

You would first have to plug in for x, (which is already given). After plugging in for x, you would need to solve the equation to get y.

Once you have both x and y, you will have your (x,y)

For example: (given x value = -5)

$f(x) = -|x - 5| -4\\f(-5) = -|(-5) - 5| - 4\\f(-5) = -|-10| - 4\\f(-5) = -10 - 4\\f(-5) = -14\\f(-5) = y = -14\\\\$

so:

x = -5

y = -14

( -5, -14)
