Answer:

[tex]\large\boxed{y=\dfrac{1}{4}x-3}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

Parallel lines have the same slope. Therefore if given line is

[tex]y=\dfrac{1}{4}x+2[/tex]

then the slope of our line is [tex]m=\dfrac{1}{4}[/tex].

We have the equation:

[tex]y=\dfrac{1}{4}x+b[/tex]

The line passes through (4, -2). Put the coordinsted pf the point to the equation:

[tex]-2=\dfrac{1}{4}(4)+b[/tex]

[tex]-2=1+b[/tex]             subtract 1 from both sides

[tex]-3=b\to b=-3[/tex]

Finally:

[tex]y=\dfrac{1}{4}x-3[/tex]
