Question

The slope of the line that passes through the points (2,4) and (-1,9) is

Answer 1

Given the points (2,4) and (-1,9)

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