On A Piece Of Paper, Graph $y - 5 \ \textgreater \ 2x - 10$. Then Determine Which Answer Choice Matches The Graph You Drew.A. Graph A B. Graph B C. Graph C D. Graph D
Understanding the Inequality
To graph the inequality , we need to first rewrite it in a more familiar form. By adding 5 to both sides, we get . This is a linear inequality in slope-intercept form, where the slope is 2 and the y-intercept is -5.
Graphing the Inequality
To graph the inequality, we need to first graph the corresponding equation . This is a line with a slope of 2 and a y-intercept of -5. We can graph this line by plotting two points on the line and drawing a line through them.
Finding the Solution Region
Since the inequality is , we need to find the region above the line . This means that any point above the line is a solution to the inequality.
Graphing the Solution Region
To graph the solution region, we can draw a dashed line to represent the boundary of the solution region. We can also shade the region above the line to indicate that it is the solution region.
Comparing with Answer Choices
Now that we have graphed the inequality, we can compare it with the answer choices to determine which one matches the graph.
