You can put this solution on YOUR website!
The x-intercept of a line is the point at which the line
crosses the x+axis, where the y value equals 0.


x-intercept+= ( x,+0 )
The y-intercept of a line is the point at which the line
crosses the y+axis, where the x value equals 0+.
y-intercept = ( 0, y )
you have:
x-4y=4
so, to find x-intercept+= ( x,+0 ), set y=0
x-4%2A0=4
x-0=4
x=4.......->....x-intercept+= ( 4,+0 )

to find y-intercept+= ( 0,+y ), set x=0
x-4y=4
0-4y=4
-4y=4
y=4%2F-4
y=-1..........->....y-intercept+= ( 0,+-1 )
let's see it on a graph:
y=%281%2F4%29x-1...your function in slope-intercept form
