I know I learned about this in my text book but I cannot find it!! O.O When graphing a linear inequality, how do you know when to use a dashed line or a solid line? And when you are graphing a linear inequality, how do you determine where to shade? Thanks guys, trying to remember how these are determined O.O I have questions I gotta figure this out on! ^.^
thats a hard one
If the inequality symbol looks like this ≥ as in y ≥ 2 or x+2y ≥ 7, then the line is solid. That is because x+2y ≥ 7 means all points x and y such that x+2y > 7 or x+2y = 7
If the inequality looks like this: y < x + 5, then there is a dashed line where y = x + 5. That is because y < x + 5 means all points x and y such that y is less than but not equal to x + 5.
