1
Q
how do you find a gradient
A
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
2
Q
what is the gradient relation between parallel lines
A
they have the same gradient
3
Q
what is the gradient relation between perpendicular lines
A
if line 1 gradient is m
line 2 = -1/m
4
Q
