What is the equation of the line that passes through (-3,-1) and has a slope of 2/5? Put your answer in slope intercept form 1. Y=2/5x+1/52. Y=2/5x-1/53. Y= -2/5x-1/5

We are asked to determine the equation of a line that passes through the point (-3, -1) and has a slope 2/5. To do that we will use the point-slope form of a line equation:

[tex]y-y_0=m(x-x_0)[/tex]

Where:

[tex]\begin{gathered} (x_0,y_0)=\text{ point on the line} \\ m=\text{ slope} \end{gathered}[/tex]

Now, we plug in the values:

[tex]y-(-1)=\frac{2}{5}(x-(-3))[/tex]

Simplifying we get:

[tex]y+1=\frac{2}{5}(x+3)[/tex]

Now, we apply the distributive law:

[tex]y+1=\frac{2}{5}x+\frac{6}{5}[/tex]

Now, we subtract 1 from both sides:

[tex]\begin{gathered} y=\frac{2}{5}x+\frac{6}{5}-1 \\ \\ y=\frac{2}{5}x+\frac{1}{5} \end{gathered}[/tex]

and thus we get the equation of the line.
