Identify the slope and y-intercept of each linear function's equation. y = 3x - 1
slope = -3; y-intercept at 1
y = 1 - 3x
slope = -1; y-intercept at 3
-X + 3 = y
slope = 1, y-intercept at -3
X-3 = y
slope = 3; y-intercept at -1
Done
Intro

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.
