16. Simultaneous equations

Simultaneous equations learning objectives: • • find the exact solutions of two simultaneous equations in two unknowns (22. 1) use elimination of substitution to solve simultaneous equations (22. 1) set up and solve a pair of simultaneous equations in two variables (22. 2) interpret a pair of simultaneous equations as a pair of straight lines and their solution as the point of intersection (22. 3) Reference Material 10 Ticks: MEP:

Linear Graphs learning objectives: • recognise that equations of the form y=mx+c correspond to straight-line graphs in the coordinate plane (15. 4) • plot and draw graphs of straight lines with equations of the form y=mx+c (15. 4) • interpret and analyse a straight line graph (15. 4) • understand that the form y=mx+c represents a straight line (15. 4) • find the gradient of a straight line from it’s equation (15. 4) Reference Material 10 Ticks: MEP:

Linear Graphs – Real life graphs learning objectives: • draw and interpret straight line graphs for real-life situations — ready reckoner graphs — conversion graphs — fuel bills, eg gas and electric — fixed charge (standing charge) and cost per unit Reference Material 10 Ticks: MEP: (15. 6)

Linear Graphs – Inequalities learning objectives: • show the solution set of several inequalities in two variables on a graph Reference Material 10 Ticks: MEP: (19. 4)
