Answer:
x - 4 = 0
Step-by-step explanation:
Slope is undefined
So, slope m = 1/0
Line is passing through the point (4, 8)
Equation of line:
[tex]y - y_{1} = m(x - x_{1} ) \\ \\ (y - 8 )= \frac{1}{0} (x - 4) \\ \\ (y - 8 ) \times 0= (x - 4) \\ \\ 0 = x - 4 \\ \\ x - 4 = 0 \: \\ is \: the \: required \: equation \: \\ line.[/tex]
