[BowTies1]

this is on gradients of lines


2) A is the point (0,1), B(8,8) C(5,3) and D(3,6) Use gradients to show that ACBD is a parallelogram

3) P is the point (1,1) q is (-1,0) R is (-2,3) and PQRS is a parallelogram. What are the gradients of lines RS and PS

4) Find the sizes of the angles that the lines joining the following pairs of paints make with OX:
a) (0,0 )and (1,root3) b) (3,4) and (5,6)

5) M is the point (a,a squared) N is (3b,9bsquared). find the gradient of MN in its simplest form


Thanks ross

Points that are facing diagonally have a gradient of 2.5
Smaller areas have a gradient of 0.25 and as both lines are parallel, they have the same gradient.


Gradient = Change in Y/Change in X

hopes this helps :)
