General formula for area of triangle is
.
Where:
is height of triangle perpendicular to base side of triangle.
is the length of base side of triangle.
Multiplying
and
results in rectangle, dividing that by 2 gives you area of a triangle.
Hope this helps.

Answer:
the graph that goes through the points
(0,3), (-4,0)
Step-by-step explanation:
make y the subject
3x-4y=-12
4y=3x+12
y=(3x+12)/4
now when x=0
y=12/4=3
so coordinates (0,3)
now when y=0
0=(3x+12)/4
by multplying both sides by 4
0=3x+12
0=3 (x+4)
divide both sides by 3
0=x+4
x=-4
so coordinates (-4,0)
