Question

Can you help me find the slope of the line using (-6,9),(7,-9)

Answer 1

`\begin{gathered} \text{The given coordinates is as follows:} \\ x_1=-6,y_1=9,x_2=7,y_2=-9 \\ \text{The formula for slope of the line is as follows:} \\ m=\frac{y_2-y_1_{}}{x_2-x_1} \\ m=(-9-9)/(7+6) \\ m=(-18)/(13)(\text{Ans)} \end{gathered}`
