Answer
To find the x-intercept of a linear equation, set $y=0$, and then solve for the value of $x$.
Work Step by Step
The x-intercept of a linear equation is the point on the x-axis where the line crosses.
Note that all points on the x-axis have a y-coordinate of $0$.
Thus, to find the x-intercept of a linear equation, set $y=0$, and then solve for the value of $x$.
Example:
To find the x-intercept of $y=2x-4$, set $y=0$, and then solve for $x$ to obtain:
$y=2x-4
\\0 = 2x-4
\\0+4=2x
\\4=2x
\\\frac{4}{2}=x
\\2=x$
Thus, the x-intercept is $2$.
