What is an equation of the line that passes through the point \( (5,-8) \) and is perpendicular to the line \( 5 x-4 y=16 ? \)
3. Use point-slope form: $y - (-8) = -\frac{4}{5}(x-5)$
Step 1 :1. Find the slope of given line: $\frac{5}{4}$
Step 2 :2. Find the slope of perpendicular line: $-\frac{4}{5}$
Step 3 :3. Use point-slope form: $y - (-8) = -\frac{4}{5}(x-5)$
