1. The problem is to analyze the line given by the equation $5x + 4y = 8$ and understand its graph.
2. The standard form of a line is $Ax + By = C$. Here, $A=5$, $B=4$, and $C=8$.
3. To find the intercepts, set $x=0$ to find the $y$-intercept and set $y=0$ to find the $x$-intercept.
4. For the $y$-intercept, set $x=0$:
$$5(0) + 4y = 8 \Rightarrow 4y = 8 \Rightarrow y = \frac{8}{4} = 2$$
5. For the $x$-intercept, set $y=0$:
$$5x + 4(0) = 8 \Rightarrow 5x = 8 \Rightarrow x = \frac{8}{5} = 1.6$$
6. The slope-intercept form is $y = mx + b$. Solve for $y$:
$$5x + 4y = 8 \Rightarrow 4y = 8 - 5x \Rightarrow y = \frac{8 - 5x}{4} = 2 - \frac{5}{4}x$$
7. The slope $m$ is $-\frac{5}{4}$ and the $y$-intercept $b$ is $2$.
8. The line crosses the $y$-axis at $(0,2)$ and the $x$-axis at $(1.6,0)$.
9. The graph is a straight line descending from left to right because the slope is negative.
10. The point $Q(0,5)$ is above the line since substituting $x=0$ gives $y=2$ on the line, and $5 > 2$.
Final answer: The line $5x + 4y = 8$ has slope $-\frac{5}{4}$, $y$-intercept $(0,2)$, $x$-intercept $(1.6,0)$, and the point $Q(0,5)$ lies above it.
