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

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

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

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