$1: y=-48$
$2: x=\frac{-9}{4}$
$3: y=\frac{5}{2}$
$4: x=2$
$5: y=5x-18$
$6: y=\frac{1}{3}x-2$
$7: x+4y=14$
$8: x-3y=9$
$9: x=5 \text{ or } x+0y=5$
$10: y=-11 \text{ or } 0x+y=-11$
$11: 3x-y=2$
$12: y=\frac{-4}{7}x-4$
$13: x=7 \text{ or } x+0y=7$
$14: y=-1 \text{ or } 0x+y=-1$
$15: m=\frac{3}{8}$
$\quad \text{The x-intercept occurs at } x= \frac{1}{3} $
$\quad \text{The y-intercept occurs at } y= \frac{-1}{8} $
$16: m=\frac{1}{2}$
$\quad \text{The x-intercept occurs at } x= 2 $
$\quad \text{The y-intercept occurs at } y= -1 $
$17: \text{The x-intercept occurs at } x= -5$
$18: \text{The y-intercept occurs at } y= \frac{16}{3}$
$19: \text{The x-intercept occurs at } x= -8 $
$\quad \text{The y-intercept is undefined} $
$20: \text{The x-intercept is undefined} $
$\quad \text{The y-intercept occurs at } y= 12 $
