You can put this solution on YOUR website!
Given line is y=-2, a horizontal line, slope 0.

Starting in point slope form,
Parallel, containing required (-4,1),
y-1=0%2A%28x%2B4%29
y-1=0
y=1, which you could find without using any algebra. This would be the same as saying for standard form, 0%2Ax%2By=1..


The perpendicular line containing (-4,1)?
No slope for this line. Vertical line! (Also, no vertical axis intercept.)
x=-4
