Write in point-slope form an equation of the line that passes through the point (1, 9) with slope −2. $$

The point slope form formula is as follows:


(1,9) can be used to replace and .
Since the slope is -2, we can use that to replace m.



If you want this to be simplified, we can use the Distributive Property:



And we can use the Addition Property of Equality to convert it to Slope intercept form:



Hope this helps! :^)
