What this unit covers

• Coordinates: Utilize and understand Cartesian coordinates in a two-dimensional space.
• Drawing linear graphs: Create straight-line graphs based on linear equations presented in the format y = mx + c (for example, y = -2x + 5), unless provided with a table of values.
• Gradient of linear graphs: Determine the slope of a straight line using a grid.
• Equations of linear graphs: Understand and derive the equation of a straight line represented as y = mx + c. Questions may involve using or identifying equations in the forms y = mx + c or x = k, determining the equation from a given graph, or finding the gradient and y-intercept from an equation, such as identifying the gradient and y-intercept from y = 6x + 3. Students should provide equations of a line in their simplest form.
• Parallel lines: Determine the slope and equation of a straight line, such as finding the equation of a line that is parallel to a specified line, for example, y = 4x - 1, which goes through the point (1, -3).
