On a coordinate plane, triangle L M N has points (negative 1, 2), (negative 1, negative 4), and (3, negative 4). What is the area of triangle LMN?

12 square units
14 square units
15 square units
24 square units

9514 1404 393

  12 square units

Step-by-step explanation:

The triangle area is given by ...

  A = (1/2)bh

This triangle has a base of 4 units and a height of 6 units, so its area is ...

  A = (1/2)(4)(6) = 12 . . . . square units

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
