how do you find a gradient
mark two accurate points on a graph. find the change in x and the change in y from p1 to p2. gradient is change in y/ change in x
what is the gradient relation between parallel lines
they have the same gradient
what is the gradient relation between perpendicular lines
if line 1 gradient is m
line 2 = -1/m
what do quadratic graphs look like
they are bucket shaped and symmetrical
