To find slope we use the formula ~

  • [tex] \sf \dfrac{y2 - y1}{x2 - x1} [/tex]

[ Ratio of the difference of y - coordinates of the points and the difference of x - coordinates of the points ]

let's find the slope of line passing through the given points ~

1. (10 , -9) and (-4 , -14)

  • [tex] \sf \dfrac{ - 9 - ( - 14)}{10 - ( - 4)} [/tex]

  • [tex] \sf \dfrac{ - 9 + 14}{10 + 4} [/tex]

  • [tex] \sf \dfrac{5}{14} [/tex]

2. (16 , 6) and (-4 , -14)

  • [tex] \sf \dfrac{6 - ( - 14)}{16 - ( - 4)}[/tex]

  • [tex] \sf \dfrac{6 + 14}{16 + 4} [/tex]

  • [tex] \sf \dfrac{20}{20}[/tex]

  • [tex] \sf1[/tex]

3. (9 , -4) and (5 , -20)

  • [tex] \sf \dfrac{ - 4 - ( - 20)}{9 - 5}[/tex]

  • [tex] \sf \dfrac{ - 4 + 20}{4} [/tex]

  • [tex] \sf \dfrac{16}{4} [/tex]

  • [tex] \sf4[/tex]

4. (-13 , 20) and (-18 , 20)

  • [tex] \sf \dfrac{20 - 20}{ - 13 - ( - 18)} [/tex]

  • [tex] \sf\dfrac{0}{ - 13 + 18} [/tex]

  • [tex]0[/tex]

I hope it helps ~
