Plot the points by giving values to
-
Let
x=-4 (To cancel out thecolor(red)(4 )
=>y=2abs(cancel(-4+color(red)(4)))-1=0-1=-1
->(color(red)(-4,-1)) -
Let
x=0
=>y=2abs(0+4)-1=8-1=7
->(color(blue)(0,7)) -
Let
y=0
=>2abs(x+4)-1=0
=>2abs(x+4)=1
=>abs(x+4)=1/2
=>x+4=-1/2 (One possibility)
=>x=-1/2-4=-9/2=-4.5
->(color(green)(-4.5,0))
