Answer:
C
Step-by-step explanation:
The pair of triangles in option C (image attached below) shows that the slope of line a is the same anywhere on the line.
Let's check it out:
Slope = rise/run
✔️For the first lower triangle:
Rise = 3.5
Run = 4.5
Slope = 3.5/4.5 ≈ 0.8
✔️For the second upper traingle:
Rise = 4
Run = 5
Slope = 4/5 = 0.8
Therefore, it shows that the slope of the line is the same anywhere along the line of the graph.

Answer:
x=4
Step-by-step explanation:
If all the figures are similar, we'll have to shrink them at the same rate as the rest.
The ratio here is 2/5. So,
2/5 = 6.4/16
2/5 = x/10
x=4
