Find the x- and y-intercepts of th eline x + 4y = 4.?

Question

I don't get the intercepts...

Answer 1

If x=0 then y must equal 1
0 + 4(1)=4

if y=0 then x must equal 4
4+4(0)=4

Your intercepts are
(0,1)(4,0)

Hope that helps.

Answer 2

When x = 0 , y = 1 gives (0,1) is y intercept
When y = 0 , x = 4 gives (4,0) is x intercept.

Answer 3

set x = 0
then 0 + 4y = 4 ==> y = 1

set y = 0
then x + (4 x 0) = 4 ==> x = 4

then x = 4 and y = 1

Answer 4

To find the y-intercept, you have to solve for y. First you have to get y on one side, like this.
4y = -x + 4
then, divide by 4.
y = -1/4x + 1
The y-intercept is 1.

To find the x-intercept, you have to solve for x. First you have to get x on one side, like this.
x = -4y + 4.
The x-intercept is 4.

Hope this helps! =]

Answer 5

To find the x intercept, plug 0 in for y and solve for x.

To find the y intercept, plug 0 in for x and solve for y.

Answer 6

x + 4y = 4
4y= 4 - x
divide by 4
y= 1 - .25x
y int = y(0) = 1-.25(0) = 1

y = 1- .25x
0 = 1- .25x
-1= -.25x
multi by -4
x=4

Answer 7

Don't you just make x=0 to find the y and y=0 to find the x, or is that to find something else.

Answer 8

make right hand side =1
to do so divide the equation by 4.
x/4 + y =1
the denominator of x and y are their intercepts
x int = 4; y-int=1

this comes from the formula x/x-int + y/y-int =1

Answer 9

yint= 1
xint= 4

Answer 10

yint - 1
xint - 4
