8. To identify lines of linear equations like
y = 4x + 2 Grade C
y = mx + c
Success Criteria – graphs of linear equations
1) Calculate the gradient using the following formula
change in y (the gradient is the m
change in x in the equation above).
2) Look at the y-intercept this shows you the
constant term (c in the above equation).
3) Put the equation together in the form y = mx + c.
