graph has a straight line boundary drawn complete the graph by shading the correct region x+y≥18
To complete the graph by shading the correct region, follow these steps:
1. Draw the straight line boundary of the graph, which is x + y = 18. To do this, determine two points on the line by choosing x and y values that satisfy the equation. For example, if x = 0, then y = 18. And if y = 0, then x = 18. So you have the points (0,18) and (18,0). Plot these points and draw a straight line passing through them.
2. Since the inequality states that "x + y ≥ 18", the region we need to shade is the one where x + y is greater or equal to 18. This means we need to shade the region above the line.
Here is the completed graph with the shaded region:
