Line a: y = 1/2 x + 2 line b: y = - 1/2 x + 7 line c: y = 2x + 4 line d: y = 1/2 x + 5/4 which lines are parallel? a) a and b b) a and c c) b and c d) a and d

the answer to the problem is C) B and C

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

the first one, all those points on the line just make a strait line.
