RECALL: (1) A point where the graph touches or crosses the x-axis is called an x-intercept. Given an equation, the x-intercept/s can be found by setting $y=0$ then solving for $x$. (2) A point where the graph touches or crosses the y-axis is called a y-intercept. Given an equation, the y-intercept/s can be found by setting $x=0$ then solving for $y$. Solve for the x-intercept/s by setting $y=0$ then solving for $x$: $\begin{array}{ccc} &xy &= &5 \\&x(0) &= &5 \\&0 &= &5 \end{array}$ The statement is false. This means that the equation's graph has no x-intercepts. Solve for the y-intercept/s by setting $x=0$ then solving for $y$: $\begin{array}{ccc} &xy &= &5 \\&(0)(y) &= &5 \\&0 &= &5 \end{array}$ The statement is false. This means that the graph of the given equation has no y-intercepts.
