The meaning of POINT-SLOPE FORM is 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.
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) and the slope of the line: m,and want to find other points on the line.Have a play with it (move the point, try ...
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 ...
