Lesson 6 - Point Slope Form

Let’s think of Manhattan as a coordinate grid where a point is defined by its street number (x) and its avenue number (y). For example, a person at the intersection of 68th street and 3rd avenue would be at the point (68 , 3). 

A cab drives along Broadway. It starts at 23rd street and 5th avenue, and it drops the person off at 44th street and 7th avenue. Use those points to write the equation of the cab’s path along Broadway in point-slope form.

Hint: To write in point slope form, you need a point and the ______?

A ship starts at a latitude (x) and longitude (y) of (58, 175). The ship wants to travel on a path so that it goes 3 degrees west for every 1 degree south. Write the equation of the ship’s path.
