Derive the equation of the straight line in the form of y = mx + c and then sketch the graph. The gradient and the coordinates of a point is given:
1) | m = 4 ; (-4 , -4) | 2) | m = 5 ; (4 , -3) |
3) | m = -3 ; (-3 , 3) | 4) | m = 4 ; (2 , 5) |
5) | m = -1 ; (3 , 0) | 6) | m = 1 ; (-5 , 3) |
7) | m = -2 ; (3 , 2) | 8) | m = -2 ; (0 , 8) |
9) | m = 2 ; (-1 , 3) | 10) | m = -1 ; (3 , -1) |
11) | m = 2 ; (-5 , 4) | 12) | m = 4 ; (1 , 4) |
13) | m = 4 ; (5 , 1) | 14) | m = -2 ; (2 , 0) |
15) | m = 4 ; (2 , 3) | 16) | m = 2 ; (5 , -2) |
