recognise (when values are given for m and c) that equations
of the form y = mx + c correspond to straight-line graphs in the coordinate
plane
find the gradient of lines given by equations of the form y = mx + c
(when values are given for m and c); |
understand that the form y = mx + c represents a straight line
and that m is the gradient of the line, and c is the value of the
y-intercept;
explore the gradients of parallel lines and lines
perpendicular to these lines |
