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

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

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