It is 1 because if you divided 7over 7 it 1 so x=1
Answer:
Option C
Step-by-step 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.
