Definition 5 An equation of the form<br />
y − y 1 = m(x − x 1 )<br />
is a linear equation in point-slope form.<br />
In general, the graph of an equation y − y 1 = m(x − x 1 ) is a line<br />
with slope m passing through the point (x 1 , y 1 ).<br />
Example: What is the point-slope equation for the line with a<br />
slope of 3 passing through the point (−4, 6)?<br />
