Students learn how to use a straight line graph so solve linear equations.
Learning progresses from solving equations where the unknown appears on one side to using the intersection of two graphs to solve equations of the form 2x + 1 = x.
Differentiated Learning Objectives
- All students should be able to use graphical methods to estimate a solution to an equation.
- Most students should be able to use linear graphs to estimate values of y for given values of x and vice versa.
- Some students should be able to use graphical methods to solve an equation in the form x = mx + c
