The two lines with gradient m1 and m2 are parallel if.
m1+m2 = 0
m1 = m2
m1 = 1/m2
m1m2 = 1
Equation of the straight line passing through the point (3,-2) with gradient -5/8 is.
8y = -5x-1
8y = -5x+1
8y = 5x-1
8y = 5x+1

The gradient of a line which is perpendicular to one with gradient
If the vertices of a triangle are A(2,1) , B (2,7) and C(-4,-1). The relationship between BC and MN where M is the mid point of AB and N is the mid point of AC is.
MN = BC
MN = 2 BC
BC = 1/2 MN
BC = 2 MN
