Please try leaving out the "I'm so bad at math" part.  It doesn't help.

The given inequality is   4x + y > −6.  Because of the > symbol, we must use a dashed line, not a solid one.  Let's solve this for y:    y > -4x - 6.

This (dashed) line has a slope of -4 and a y-intercept of (0,-6).

Plot (0,-6).  Then, with your pencil pt. on that, move 1 unit to the right and then 4 units down.  Plot a new point there, at (1, -10).  Draw your dashed line thru those 2 pts.  Then, because we have y > -4x - 6, shade the area ABOVE this line.  Done.
