Answer:
Option C
Explanation:
From the graph attached,
Slope of the line passing through two points A and B will be,
m =

=

=

Triangles having same ratio of Height and base (slope) will lie on the line graphed.
Option A
Slope pf the triangle =

Slope of the line ≠ Slope of the triangle
Therefore, triangle will not lie on the line.
Option B
Slope of the triangle =


Triangle will not lie on the line.
Option C
Slope of the triangle =

Since, slope of the line = slope of the triangle
Triangle will lie on the line.
Option D
Slope of the triangle =

But

Therefore, triangle will not lie on the given line.
