Answer 5

function f(x) = 4x - 3?

f(x) is the "y" value on the graph. So this is
y= 4x-3

try a few points: if x is 0, what is y? any idea ?

Answer 6

I'm just really bad at graphs But i got B

Answer 7

y= 4x-3
if x is 0, what is y? any idea ?

Answer 8

-4

Answer 9

?

Answer 10

do you know how to replace the x with 0: erase the x, and write in 0 in
y = 4*x-3
then simplify. what do you get ?

Answer 11

-12

Answer 12

remember "order of operations"
you do the multiply first, then the add or subtract.

Answer 13

-3

Answer 14

jj found the answer: when x=0 you do
y = 4*0 - 3
4 times 0 is 0, so y= 0-3
and that is y=-3

so (0,-3) is on the line.

can yo find (0,-3) ? you put your finger on the x-axis (horizontal line) at 0
move down 3 steps.
which line do you get to ?

Answer 15

line R

Answer 16

wouldnt it be line s
