Scientists construct and interpret figures regularly, but this is a skill that is often difficult for students to master. TIEE puts great emphasis on making and analyzing figures because this ability ...
If we are given equation of the line instead of the graph, we can still determine the gradient. Equations of straight-line graphs are given in the form: \(\text{y = 2x - 1}\) The gradient is 2 and the ...
where a, b, c and d represent numbers. For example, \(\text{x = 3}\), \(\text{y = -7}\), \(\text{y = 5x + 11}\) Lines in the form \(\text{x = a}\) will always be ...
