Yes. (1 , 0)

#### Work Step by Step

Every point that is in the X-axis has a $y$ coordinate equal to $0$. To find the x-intercept in $y=log_2x$, you have to make $y=0$ Doing as above, we have $0=log_2x \longrightarrow 2^{0}=x \longrightarrow 1=x$ Therefore when $y=0 \longrightarrow x=1$, thus the coordinates of the x-intercept are (1 , 0)
