The table represents the function f (x) = 5x – 8. Find f (–4):

f (–4) = 5(–4) – 8

f (–4) = –28

A 2-column table with 4 rows. Column 1 is labeled x with entries negative 4, negative 2, 3, 7. Column 2 is labeled f (x) with entries negative 28, a, b, c.

Use the drop-downs to choose the value for the variables in the table.

a =
b =
c =
i dont know how to put the table on here lol

step-by-step explanation:

what are you trying find out?

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
