x-intercept: $(1, 0)$ y-intercept: $(0, -10)$

Work Step by Step

Find the x-intercept by setting $y=0$ then solving for $x$: $10x-y=10 \\10x-0=10 \\10x=10 \\\frac{10x}{10}=\frac{10}{10} \\x=1$ The x-intercept is $(1, 0)$. Find the y-intercept by setting $x=0$ then solving for $y$: $10x-y=10 \\10(0)-y=10 \\-y=10 \\-1(-y) = -1(10) \\y=-10$ The y-intercept is $(0, -10)$.
