Question 1189324
Find the equation of the line with slope -12/5 crosses the first quadrant and forms with the axes a triangle with 
the perimeter of 15 units.
a. 12x  -  5y = 30
b. 12x + 5y = 30
c. -12x + 5y = 30
d. 12x + 5y = -30
----------------------
a & c have positive slopes
d does not cross Q1
=====================
b is the only possibility of the 4.
I didn't check for the perimeter.
