The triangle that has vertices at M - 4 ,   0 ,   N 3 ,   - 1 ,     a n d   Q ( 2 ,   4 ) has been boxed in, as shown. Find the area of ∆ M N Q . Exercises 33, 34.

To determine

To find:

The area of MNQ and the vertices are M-4, 0, N3, -1, and Q(2, 4).

Explanation

Given vertices are,

M-4, 0, N3, -1, and Q(2, 4)

Given figure is,

Sketch the points and draw the triangle in the graph as shown in figure,

Base of the triangle can be determined by subtracting x-coordinates of MN

Base MN=3--4=7

Height of the triangle can be determined by subtracting
