Answer :
Start finding the slope of the line
[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \text{then,} \\ m=\frac{5-4}{3-(-2)} \\ k=\frac{1}{5} \end{gathered}[/tex]using one of the points find the intercept and the standard form
[tex]\begin{gathered} (-2,4) \\ 4=\frac{1}{5}(-2)+b \\ b=4+\frac{2}{5} \\ b=4.4 \end{gathered}[/tex]the equation of the line is
[tex]y=\frac{1}{5}x+4.4[/tex]
