Given: 8x+2y-8=0 and (?,8)

Since we are looking for the x coordinate and are given the y coordinate (y=8), we can solve for x by plugging in y=8 into the given equation.

8x+2(8)-8=0
8x+16-8=0
8x+8=0
Subtract 8 from both sides
8x= -8
Divide both sides by 8 to solve for x
x=1 is the missing coordinate: (1,8)
