Hi there!

I believe your answer is:  

(-2, 0)

Here’s why:  

⸻⸻⸻⸻

$\text{Substitute in \textbf{0} for } y \text{ and solve for } x\text{.}\\-------------------\\y = 2x+4\\-------------------\\\rightarrow 0 = 2x +4\\\\\rightarrow 2x + 4 = 0\\\\\rightarrow 2x +4 - 4 = 0 - 4\\\\\rightarrow 2x = -4\\\\\rightarrow\frac{2x=-4}{2}\\\\\rightarrow \boxed{x=-2}$

$\text{The \textbf{x-intercept} of the given equation is: } (-2, 0)$
