Find the area of a triangle formed by the x-axis, the line y=-6x+60, and the line 3x-4y=-24.
------------
Find where the 2 lines intersect.
y = -6x+60
3x-4y = -24
Sub for y in 2nd eqn
3x - 4(-6x+60) = -24
3x + 24x-240 = -24
27x = 216
x = 8
---------
y = -6x+60 = 12
--> (8,12)
-----------------
Find the x-intercepts of the 2 lines by setting y=0.
y = -6x+60
0 = -6x+60
x = 10
----------
3x-4y = -24
3x = -24
x = -8
--------
The base of the triangle is from x = -8 to x = 10, = 18 units.
The height is the y value of the intersection, = 12
Area = b*h/2 = 18*12/2
Area = 108 sq units.
