What is the slope of the line ? ( question 1/4 )
yanalaym [24]

\huge \rm༆ Answer ༄

First Consider two points ~ (0 , -3) and (-1 , 0)

Now, use the given formula to calculate slope :

  • \sf \dfrac{y2 - y1}{x2 - x1}

  • \sf \dfrac{0 - ( - 3)}{ - 1 - 0}

  • \sf \dfrac{ 0 + 3 }{ - 1}

  • \sf \dfrac{3}{ - 1}

  • \sf - 3

Therefore, the slope of the graph is -3
