  Course 3 • Chapter 3 Equations in Two Variables 41 Lesson 4 Reteach Slope-Intercept Form Linear equations are often written in the form y = mx + b. This is called the slope-intercept form. When an equation is written in this form, m is the slope and b is the y-intercept. Example 1 State the slope and the y-intercept of the graph of y = x – 3.

  Linear simultaneous equations with two unknowns In Chapter 3 it was seen that simultaneous linear equations in two variables could be solved by using matrices. Using your CAS calculator will result in some outcomes that you need to be able to understand. In this chapter, systems of equations for which the matrix of the coefficients is singular are
