High School Mathematics
Master advanced mathematics with high school resources including algebra, geometry, trigonometry, calculus, and statistics.
Grade 9 Mathematics
4 lessonsLinear Equations
Learners solve linear equations with parentheses, fractions and variables on both sides and set up equations to solve problems.
Linear Functions and Slope
Learners find and interpret the slope and intercept of straight-line graphs, write equations in slope-intercept form and model linear situations.
Scatter Plots and Correlation
