The coordinates of the vertices are (-1, 6), (1, 2) and (2, 3)
The coordinates of each vertex?
The functions are given as:
y = x + 1
2x + y = 4
x + y = 5
Next, we plot the graph of the lines (see attachment)
From the attached graph, the coordinates of the vertices are (-1, 6), (1, 2) and (2, 3)
The type of triangle
Rewrite the equations in slope intercept form
y = x + 1 ⇒ Slope = 1
y = -2x + 4 ⇒ Slope = -2
y = -x + 5 ⇒ Slope = -1
The equations y = x + 1 and y = -x + 5 have their slopes to be opposite reciprocals
This means that the lines are perpendicular (they form a right angle)
Hence, the triangle is a right triangle
