I just need help completing the table.

Step-by-step explanation:

Given the function f(x)=x-3

So we want to know the value of the function when

1. x=1

Then, f(x) =x-3

Let substitute x=1

f(1)=1-3

f(1)=-2

2. x=2

Then, f(x) =x-3

Let substitute x=2

f(2)=2-3

f(2)=-1

3. x=4

Then, f(x) =x-3

Let substitute x=4

f(4)=4-3

f(4)=1

4. x=5

Then, f(x) =x-3

Let substitute x=5

f(5)=5-3

f(5)=2

5. x=8

Then, f(x) =x-3

Let substitute x=8

f(8)=8-3

f(8)=5

f(x)=x-3

x. 1 2 4 5 8

f(x). -2 -1 1 2 5

slope is 35 and 20 miles is the y-intercept.
