Please refresh the page for a new set of questions.

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 are given:
1)m = -3 ; (-5 , 3)2)m = -1 ; (-1 , 2)
3)m = -5 ; (5 , 6)4)m = -3 ; (3 , 4)
5)m = 4 ; (-4 , -6)6)m = -5 ; (2 , -6)
7)m = 4 ; (6 , 4)8)m = -5 ; (2 , -4)
9)m = -4 ; (-4 , -1)10)m = -4 ; (0 , -5)
11)m = -3 ; (4 , 0)12)m = -2 ; (6 , 8)
13)m = 2 ; (6 , 1)14)m = 4 ; (-2 , 7)
15)m = 4 ; (-2 , -2)16)m = -2 ; (-1 , -1)
17)m = 2 ; (4 , 8)18)m = -5 ; (6 , -6)
19)m = -4 ; (5 , 4)20)m = -4 ; (-1 , -3)

Derive the equation of the straight line in the form of y = mx + c, from the coordinates of the two points:

1)(-5 , 4) , (-5 , 9)2)(-2 , 4) , (-5 , 2)
3)(4 , 5) , (-5 , 5)4)(4 , 5) , (-5 , -1)
5)(4 , 5) , (-7 , 9)6)(0 , 6) , (-5 , 10)
7)(4 , 8) , (-6 , 6)8)(0 , 8) , (-6 , 6)
9)(-5 , 7) , (-7 , 5)10)(-1 , 8) , (-7 , 4)
11)(-5 , 4) , (-5 , 6)12)(0 , 7) , (-7 , 1)
13)(1 , 7) , (-5 , 6)14)(-6 , 8) , (-7 , 10)
15)(-4 , 8) , (-6 , -3)16)(-4 , 4) , (-7 , 8)
17)(-5 , 5) , (-6 , 4)18)(-1 , 7) , (-7 , 5)
19)(6 , 4) , (-7 , 4)20)(-1 , 8) , (-5 , 9)
