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

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

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

To err is human, to remember them in order, statistics; to plot them Excel!
