What is the slop parallel to 8X plus 4Y -9?

To find the slope of the equation (8X + 4Y - 9 = 0), we first rearrange it into slope-intercept form (Y = mx + b). This gives us (4Y = -8X + 9), or (Y = -2X + \frac{9}{4}). The slope (m) is (-2). Therefore, any line parallel to this one will also have a slope of (-2).
