Line 1:
y=5-x
x = 0, y = 5.
y = 0, x = 5.

Line 1 is ready.

Line 2.

y = 0

Line 2 is ready.

Line 3.

2y = 3x
y=3/2x

x = 0, y = 0,
x = 2, y = 3.

Line 3 AND line 1 intersect in the vertex. Therefore, y1 = y2,
3/2x = 5-x,
x = 2.
y = 3.

Triangle has base = 5, height = 3. 3*5/2 = 7.5

y=0 is the straight line at x axis
(2/3)y=x intersects x=5-y at:
(2/3)y=5-y
2y=15-3y
y=3, this is the height

y=3/2x intersects x axis at (0,0)
y=5-x intersects x axis at (0,5)
So 5 is the base.

Area = 1/2 * 5 * 3 = 7.5
