Answer:
Step-by-step explanation:
For any two points [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] on a line, the slope of the line can be found with the following equation:
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
From the given equation, the two points are [tex](1, -2)[/tex] and [tex](3, 6)[/tex].
Plugging these two points into the equation give us the following:
[tex]\frac{6 - (-2)}{3 - 1}[/tex]
[tex]\frac{6 + 2}{3 - 1}[/tex]
[tex]\frac{8}{2}[/tex]
[tex]4[/tex]
