# Number and Algebra

Students explore the relationship between graphs and equations, sketch linear and simple non-linear graphs and solve linear equations. They find the distance between two points, midpoint and gradient of a line segment located on a Cartesian plane. Students apply index laws to numerical expressions with integer indices, apply the index laws to variables and express numbers in scientific notation. Students apply the distributive law to the expansion of algebraic expressions, including binomials, and collect like terms where appropriate.
