To find the equation of the line that is parallel to \(3x + 4y = 5\) and passes through the point \((3, -2)\), first, we need the slope of the given line. Rewriting it in slope-intercept form gives us \(y = -\frac{3}{4}x + \frac{5}{4}\), so the slope is \(-\frac{3}{4}\). Thus, the equation of the parallel line passing through \((3, -2)\) can be expressed as: \[ y - (-2) = -\frac{3}{4}(x - 3) \] Simplifying this leads to: \[ y + 2 = -\frac{3}{4}x + \frac{9}{4} \] \[ y = -\frac{3}{4}x + \frac{1}{4} \] Next, for the line that is perpendicular to \(3x + 4y = 5\), the slope will be the negative reciprocal of the original slope. The slope of the original line is \(-\frac{3}{4}\), thus the perpendicular slope is \(\frac{4}{3}\). Using the point \((3, -2)\), the equation for the perpendicular line is: \[ y - (-2) = \frac{4}{3}(x - 3) \] Simplifying this gives: \[ y + 2 = \frac{4}{3}x - 4 \] \[ y = \frac{4}{3}x - 6 \] So, the equation of the perpendicular line is: \[ y = \frac{4}{3}x - 6 \]
