Question

Graph using the Slope and the Y-Intercept.
4x-y=-4

Answer 1

Help

Answer 2

put it in slope-intercept form
y = mx + b

Answer 3

m=slope
b = y-intercept

Answer 4

do you know how to solve equation for 1 variable?
in other words get y by itself

Answer 5

No, I really need help. How would I put the numbers in the formula?

Answer 6

theres no formula, just an equation
you just have to move things around so it looks like y=mx +b
its a 2-step process
1) move x term to other side, flip the sign
2) divide by coefficient of y on both sides, include every term

Answer 7

thansk

Answer 8

your welcome
what did you get
y = ?

Answer 9

im still working on it, but am a little confused, i need to find -4x-y=-4 but i dont know where to Put the numbers in the formula? What did you get? So this way i can go over mines and fix the errors that i have comitted,

Answer 10

ok the goal is to graph this line, 4x -y=-4 represents a line
so we are not plugging in any numbers into a formula
use algebra to get y by itself, then you can identify slope, y-intercept
this then allows you to plot the points needed to graph the line

Answer 11

if you have to, just make a x,y chart and plot points that way to get your line

Answer 12

oh okay

Answer 13

if x = 1, what does y equal ?

Answer 14

-8?

Answer 15

rite?

Answer 16

i get positive 8
4(1) -y = -4
-y = -8
y = 8

Answer 17

oh okay, im sorry i forgot about the negative signs.

Answer 18

pay attention to those neg signs
ok now pretend the 1 is x
what does y equal

Answer 19

4x - y = -4
subtract 4x on both sides
-y = -4x -4
divide by -1
y = 4x + 4
this is slope intercept form
m = 4
b = 4
Now you can graph it
