: the equation of a straight line in the form y − y1 = m(x − x1) where m is the slope of the line and (x1, y1) are the coordinates of a given point on the line compare slope-intercept form Word History First Known Use 1904, in the meaning defined above Time Traveler ...
Up until now, we have been using the slope-intercept form of a linear equation to describe linear functions. Here, we will learn another way to write a linear function, the point-slope form. y−y1=m(x−x1)y−y1=m(x−x1) The point-slope form is derived from the ...

The point-slope form of the equation of a straight line is: y y1 = m(x x1). The equation is useful when we know: one point on the line: (x1, y1). m,.
The point-slope form of the equation is where m is the slope and (x1, y1) is point on the line.II.Using the Point−Slope Form to Write the Equation of a Line A.Given a point and slope: plug info into the equation.Example: slope= 4, passing through (2, 5)y − y1 ...
