This is in the 3rd quadrant, so -12 is the adjacent side of the 5,12,13 triangle.
Cot(theta) = -12/(-13) = 12/13
Their distance differs by 15 miles for each hour of travel time. Thus, the travel time of interest is
.. (180 -144) miles/(15 miles/hour) = 2.4 hour
The red car's speed is 180 mi/(2.4 h) = 75 mi/h.
The blue car's speed is 144 mi/(2.4 h) = 60 mi/h.
You need to fin b
remember y=mx+b
(1,3)
m=-4x
y=3
3=-4(1)+b
3=-4+b
b=7
final answer
y=-4x+7
