Given the points (2,4) and (-1,9)
[tex]\begin{gathered} X_1=2;Y_1=4 \\ X_2=-1;Y_2=9 \end{gathered}[/tex][tex]\begin{gathered} \text{Slope, M of a line is given by the equation;} \\ M=\frac{Y_2-Y_1}{X_2-X_1} \\ M=\frac{9-4}{-1-2} \\ M=\frac{5}{-3} \\ M=\frac{-3}{5} \end{gathered}[/tex][tex]\text{Hence the slope of the l}ine\text{ }is\text{ }\frac{-3}{5}[/tex]
