Question

Please help me on this problem (below the last line is this ( =____ ) couldn’t fit it into the photo)

Answer 1

The slope of a line is calculated with the following formula

`\begin{gathered} slope=(y_2-y_1)/(x_2-x_1) \\ \end{gathered}`

From our exercise we have the following 2 points

`\begin{gathered} (1,6)\to(x_1,y_1_{}_{}) \\ (2,3)\to(x_2,y_2) \end{gathered}`
`slope=\frac{3_{}-6_{}}{2-1_{}}`
`\begin{gathered} slope=\frac{-3_{}}{1_{}} \\ slope=-3_{} \end{gathered}`
