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

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

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

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