The line $\dfrac{x}{4} + \dfrac{y}{6} = 1$ meets the x-axis at P(4, 0) and y-axis at Q(0, 6). Mid-point $= \left(\dfrac{4+0}{2}, \dfrac{0+6}{2}\right) = **(2, 3)$. Answer: A
Set y = 0 to find P (x-intercept) and x = 0 to find Q (y-intercept), then apply the midpoint formula $\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)$. This is a direct application of the midpoint formula from Chapter 7.
