Watch this … WebPoint-slope Form of an Equation of a Line. The point-slope form of an equation of a line with slope m and containing the point (x1, y1) is: y − y1 = m(x − x1) We can use the point-slope form of an equation to find an equation of a line when we know the slope and at least one point. Then, we will rewrite the equation in slope-intercept form. WebAnswer: Lines with the same slope are parallel and if the slope of one line is the negative reciprocal of the second line, then they are perpendicular.
