Question

PLEASE HELP


graph each equation using x- and y-intercepts

-4x+y= -12

Answer 1

okay so y intercept is when x=0

Answer 2

and x intercept is when y =0

Answer 3

so both would be equal 0

Answer 4

thats how u build the axis lines

Answer 5

no for the y intercept u set x=0 and see what y is

Answer 6

-4x+y= -12
this equaton is representing all the points (x,y) and its telling u a rule for the x and ys

so if u have x=0
(0,?)
we must see what y is at that point that still satisfies the rule of our line

Answer 7

you can find the x intercept now

Answer 8

hope this hlped bye :)

Answer 9

yes thank you so the x would be 4?

Answer 10

-4x+y= -12
-4*0+y=-12
y=-12
(0,-12) is known as the y intercept because it passes thru the x=0 line or the y axis

Answer 11

so the x would be 0?

Answer 12

work for the x intercept
-4x+y= -12
y=0

-4x+0= -12
x=-12/-4
x=3
(3,0) is the x intercept

Answer 13

oh okay thank you :)
