Find the slope of the line that passes through (-31, 26) and (4, 36).

Sagot :

The slope of a line can be calculated with the following formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

You know that the line passes through the following points:

[tex]\mleft(-31,26\mright);(4,36)[/tex]

For this case, you can set up that:

[tex]\begin{gathered} y_2=36 \\ y_1=26 \\ x_2=4 \\ x_1=-31 \end{gathered}[/tex]

Then, knowing the coordinates shown above, you can substitute them into the formula in order to find the slope of the line. This is:

[tex]\begin{gathered} m=\frac{36-26}{4-(-31)} \\ \\ m=\frac{10}{35} \\ \\ m=\frac{2}{7} \end{gathered}[/tex]

The answer is:

[tex]m=\frac{2}{7}[/tex]
