WebParallel lines are lines that never intersect. The slopes of parallel lines are the same. To prove that two lines are parallel, we find their slope and verify that those slopes are equal. 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 ...
