How do write the Slope-intercept inequality for a graph?

Answer 1

First, write the equation of the line of the graph. Next, if the line is solid, it means equal to. If it is dotted: not equal to. Lastly, the shaded portion of a graph is where the points satisfy the equation. So pick a point in the shaded region, plug it in, and put the appropriate larger than, or less than sign to make the statement true.

EX: plug in (3,1) to y _ 3x+1

1 _ 10, then 1 < 10

So, y < 3x + 1 (add [or equal to] if the line is solid)
