The Deep Dive
To derive the required equations, let's begin by finding the slope of the given line \( 2x - 9y - 4 = 0 \). First, we can rewrite this in slope-intercept form (y = mx + b): 1. Rearranging the equation: \[ 9y = 2x - 4 \] \[ y = \frac{2}{9}x - \frac{4}{9} \] From this, we see that the slope \( m \) is \( \frac{2}{9} \). Since we need a line parallel to this one, it will have the same slope. Given the point \( (-4, 5) \), we can use the point-slope formula: The equation of the line in point-slope form is: \[ y - 5 = \frac{2}{9}(x + 4) \] Now, let's convert this to general form. Start with the point-slope form: \[ y - 5 = \frac{2}{9}(x + 4) \] Multiply through by 9 to eliminate the fraction: \[ 9(y - 5) = 2(x + 4) \] \[ 9y - 45 = 2x + 8 \] Rearranging gives us: \[ 2x - 9y + 53 = 0 \] Thus, the equation of the line in general form is: \[ 2x - 9y + 53 = 0 \]
