1. how is graphing a linear inequality on a coordinate plane similar to graphing an inequality on a number line?

An inequality on a number lines, the solution is a ranges of points. An inequality on a coordinate plane, the solution is a region of points.

On a number line, you find the points where the equality would be equal and then mark ranges above or below that point or if you have multiple points of equality, you may also mark the area between them. On a coordinate plots, you mark where the graph of an equality would be graphed and then, shade the region above or below the curve or line or if youi have multiple curves or line of an equality, then shade the region between them. -Yahoo Answers

Graphing a linear inequality on a coordinate plate is similar to graphing a inequality on a number line because of the straight line that is shown graphically on the coordinate line with all the point on that line.

Same length is comparing because it’s saying its the same and not different
