1. The problem asks to find the y-intercept of the straight line given by the equation $$3x - 4y = 24$$. 2. The y-intercept occurs where the line crosses the y-axis, which means at $x=0$. 3. Substitute $x=0$ in the equation: $$3(0) - 4y = 24$$ $$-4y = 24$$ 4. Solve for $y$: $$y = \frac{24}{-4}$$ $$y = -6$$ 5. Therefore, the y-intercept is at the point $(0, -6)$.
