Need some help on a Graphing linear function

for the second one f(x) = x+5 for the first term it would be -1

Step-by-step explanation:

you basically just plug in the numbers.

if you have the equation f(x) = x+5 and you're trying to figure out what it is when x = -6 you just put -6 where x is in the equation so it would be f(x) = -6 + 5. Then you would do that with the rest of the numbers on the table. After that you graph each point and connect them to make a line.

the answer is d. 75%
