Straight Line - gradient
Straight Line - gradient
In Secondary, we learnt that Gradient can be calculated using the ratio of the vertical change and the horizontal changes.
In Secondary 3, we are going to find the Gradient of a straight line given the coordinates of two points.
Find the gradient of the the line passing through each of the following pairs of point: (a) A (2, 3) and B(7,5) (c) E (0,0) and F(-2,1) (d) G (2, -3) and H(1, 7) (e) I (-2, 4) and J(-5, 8)
(b) C (-2, 8) and D(1, -1)
