Find the focus or directrix of a parabola

Full solution

Q. Look at the system of inequalities.

\newline

y \leq -\frac{1}{4}x + 2

\newline

x \geq 0

\newline

y \geq 0

\newline

The solution set is the triangular region where all the inequalities are true.

\newline

What are the vertices of that triangular region?

Find Intersection of Equations: First, let's find the intersection of $y \leq -\frac{1}{4}x + 2$ and $x \geq 0$ . Set $x = 0$ in the first inequality. $y \leq -\frac{1}{4}(0) + 2$ $y \leq 2$ So, one vertex is at $(0, 2)$ .
Find Another Intersection: Next, find the intersection of $y \leq -\frac{1}{4}x + 2$ and $y \geq 0$ . Set $y = 0$ in the first inequality. $0 \leq -\frac{1}{4}x + 2$ Multiply both sides by $4$ to get rid of the fraction. $0 \leq -x + 8$ Add $x$ to both sides. $x \leq 8$ So, another vertex is at $(8, 0)$ .
Find Origin Intersection: Finally, find the intersection of $x \geq 0$ and $y \geq 0$ . This is simply the origin, where both $x$ and $y$ are zero. So, the last vertex is at $(0, 0)$ .
