Answer :
The slope of the line passing through the two points [tex](1,2)[/tex] and [tex](3,8)[/tex] is [tex]\frac{3}{1}[/tex] i.e. [tex]3[/tex]
The formula for finding the slope when two points are given
[tex]y=\frac{y_{2} -y_{1} }{x_{2} -x_{1} } \\y=\frac{8-2}{3-1} \\y=\frac{6}{2} \\y=\frac{3}{1}\\y=3[/tex]
The slope of the line is [tex]3[/tex]
