<h3 /><h3>\huge \rm༆ Answer ༄</h3>

To find slope we use the formula ~

  • \sf \dfrac{y2 - y1}{x2 - x1}

[ 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 ~

<h3>1. (10 , -9) and (-4 , -14) </h3>

  • \sf \dfrac{ - 9 - ( - 14)}{10 - ( - 4)}

  • \sf \dfrac{ - 9 + 14}{10 + 4}

  • \sf \dfrac{5}{14}
<h3>2. (16 , 6) and (-4 , -14)</h3>

  • \sf \dfrac{6 - ( - 14)}{16 - ( - 4)}

  • \sf \dfrac{6 + 14}{16 + 4}

  • \sf \dfrac{20}{20}

  • \sf1
<h3>3. (9 , -4) and (5 , -20)</h3>

  • \sf \dfrac{ - 4 - ( - 20)}{9 - 5}

  • \sf \dfrac{ - 4 + 20}{4}

  • \sf \dfrac{16}{4}

  • \sf4

<h3>4. (-13 , 20) and (-18 , 20)</h3>

  • \sf \dfrac{20 - 20}{ - 13 - ( - 18)}

  • \sf\dfrac{0}{ - 13 + 18}

  • 0

I hope it helps ~
