The slope of the line that passes through ( 1,2 ) and ( 2,4 ) is 2
Step-by-step explanation:
We need to find the slope of the line that passes through ( 1,2 ) and ( 2,4 )
The formula used to find slope is:
[tex]slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
From given data:
[tex]x_{1}=1,y_{1}=2,{x_{2}=2,y_{2}=4[/tex]
putting values in the formula of slope:
[tex]slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\slope=\frac{4-2}{2-1}\\slope=\frac{2}{1}\\slope=2[/tex]
So, the slope of the line that passes through ( 1,2 ) and ( 2,4 ) is 2
