The equation of the line passing through the point $(-3, 2)$ and parallel to the $x$-axis is:

If $k = \frac{a+b}{ab}$ is a non-zero constant,then the point which lies on the straight line $\frac{x}{a} + \frac{y}{b} = 1$ is

If the slope of a line is $2$ and it makes an intercept of $-4$ on the $y$-axis,then its equation is:

Two points $(a, 0)$ and $(0, b)$ are joined by a straight line. Another point on this line is:

Let $PS$ be the median of the triangle with vertices $P(2, 2)$,$Q(6, -1)$,and $R(7, 3)$. The equation of the line passing through $(1, -1)$ and parallel to $PS$ is

If three points $(h, 0), (a, b),$ and $(0, k)$ lie on a line,show that $\frac{a}{h} + \frac{b}{k} = 1$.
