Slope of Parallel Lines

Slope of a line is the value of the angle that a straight line makes with the positive direction of x-axis in the anticlockwise sense. Slope is also refer to as Gradient.

Basically for any straight line y = mx + b , m is referred to as slope.

Parallel lines are the lines that lie in the same plane have the property that they never intersect each other. They never meet at a point. They are always the same distance apart.

Slope of Parallel lines : Property

Parallel lines have the value of the angle made with the x axis always same.. they always have the same slope.

Slopes of two parallel lines are equal.

Let the equation of two lines be y=(m1)x + c1 and y=(m2)x + c2 where m1 and m2 are slopes of the lines. The two lines are parallel if and only if m1 = m2.
