Someone give me answers & an explanation!

all work is pictured and shown

a = -18

b = 7

c = 27

Step-by-step explanation:

given f(x) = 5x - 8

Simply go down the table and substitute each value of x into the function and report the final

when x = -4,

f(-4) = 5(-4) - 8 = -28

when x = -2

f(-2) = 5(-2) - 8 = -18 (Answer a)

when x = 3

f(3) = 5(3) - 8 = 7  (Answer b)

when x = 7

f(7) = 5(7) - 8 = 27  (Answer c)

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
