Gradient = the steepness of a line 1 of 14 Gradient = 2 One across = 2 up 2 of 14 Gradient = 3 One across = 3 up 3 of 14 Gradient = 1/2 2 across, 1 up 4 of 14 Gradient = -2 1 across , 2 down 5 of 14 Gradient = rise divided by run Difference in Y divided by Difference in X 6 of 14 Straight lines All straight lines take the form Y = MX + C 7 of 14 Gradient and Intercept M = the Gradient C = -Y intercept 8 of 14 Examples of Linear Equations X -2 -1 0 1 2 Y -5 -3 -1 1 3 Y=2X-1 9 of 14 More complicated examples of how to find the gradi X Y X Y {3,4} , {5,10} 10-4 divided by 5 - 3 + 6/2 =3 10 of 14 Examples of how to find Gradient and Intercept Y=4X = 5 M=4 C=5 ={0,5} 11 of 14 How to rearrange Formuale Make N the subject: N = M=2n = 5 -5 -5 M-5 = 2n = n m-5 divided by 2 12 of 14 Another example of how to rearrange Formulae 2 {4x = 1} = 3y 8x + 2 = 3y -2 -2 8x=3y-2 d 8 d 8 x=3y - 2 d by 8 {d= divide by} 13 of 14 THINGS TO REMEMBER !!!! 1. 2 minuses = a positive 2. m is the gradient 3. c is the y intercept 14 of 14
