In a math 8B test on graphing linear equations, students may be expected to demonstrate their understanding of how to graph a linear equation in slope-intercept form (y = mx + b) by identifying the slope and y-intercept, plotting points, and drawing a straight line that represents the equation. They may also be asked to use the graph to solve for specific points or to determine if two linear equations are parallel, intersecting, or coincide.
Some possible units that may be covered in a test on graphing linear equations in math 8B include:
1. Understanding slope and y-intercept
2. Graphing lines using slope-intercept form
3. Determining the slope and y-intercept from a graph
4. Finding the equation of a line given two points
5. Recognizing parallel and perpendicular lines
6. Identifying linear equations in standard form (Ax + By = C)
7. Solving systems of linear equations graphically
Overall, students may be assessed on their ability to accurately graph linear equations, interpret the graphs, and solve problems related to linear functions, equations, and inequalities.
