$x$-intercept: $9$ $y$-intercept: $9$

To find the $x$-intercept of an equation in standard form, we plug in $0$ for $y$, and solve for $x$. $x+0=9$ We apply the identity property of addition: $x=9$ To find the $y$-intercept of an equation in standard form, we plug in $0$ for $x$, and solve for $y$. $0+y=9$ We apply the identity property of addition: $x=9$
