Answer

The $x-$ intercept is $\frac{2}{3}$. The $y-$ intercept is $-\frac{1}{3}$.

Work Step by Step

The given linear equation is $\Rightarrow 3x-6y=2$ $x$ intercept. Substitute $0$ for $y$. $\Rightarrow 3x-6(0)=2$ Simplify. $\Rightarrow 3x-0=2$ $\Rightarrow 3x=2$ Divide each side by $3$. $\Rightarrow \frac{3x}{3}=\frac{2}{3}$ Simplify. $\Rightarrow x=\frac{2}{3}$ The $x-$ intercept is $\frac{2}{3}$. $y$ intercept. Substitute $0$ for $x$. $\Rightarrow 3(0)-6y=2$ Simplify. $\Rightarrow 0-6y=2$ $\Rightarrow -6y=2$ Divide each side by $-6$. $\Rightarrow \frac{-6x}{-6}=\frac{2}{-6}$ Simplify. $\Rightarrow x=-\frac{1}{3}$ The $y-$ intercept is $-\frac{1}{3}$.
