Question

The following points are the vertices of a traingle: (0,4), (4,0), (-4,0)

a. Write a system of a linear inequalities so that the graph of the solutions of the system represents the triangle.

b. Find the area of the triangle. ​

Answer 1

b. A = 1/2 b h
A = 1/2 (8)(4)
A = 16 square units

a. y = x + 4, -4 less than or equals x less than or equals
y = -x + 4, 0 less than or equals x less than or equals 4
y = 0 , -4 less than or equals x less than or equals 4
