Write a rule for the linear function in the table.
mojhsa [17]

Answer: BRAINLY

f(x)=x-4 is the answer i believe

Answer :

The function is  

Step-by-step explanation:

Given values in table :

x        f(x)

3         -1

4          0

5          1

6          2

Here we see there is a difference of 4 in the values of x and f(x)

i.e. 3-(-1)=4

or 4-0=4

Similarly 5-1=4

6-2=4

So x-F(x)=4

Adding F(x) -4 both sides

x-F(x) +F(x) -4=4+F(x) -4

We have F(x)= x-4

Answer:

d=10

Step-by-step explanation:

Distance Formula: d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Used to find the distance between 2 points.

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

d=\sqrt{(7-1)^2+(-7-1)^2}

d=\sqrt{(6)^2+(-8)^2}

d=\sqrt{36+64}

d=\sqrt{100}

d=10
