If the comparison of slopes of two lines is found to be equal the lines are considered to be parallel. For this, firstly we have to determine the equations of the lines and derive their slopes.
WebParallel Lines Equation. The equation of a straight line is generally written in the slope-intercept form represented by the equation, y = mx + b, where 'm' is the slope and 'b' is the y-intercept. The value of 'm' determines the slope or gradient and tells us how steep the line is. It should be noted that the slope of any two parallel lines is ... Webcontributed.
