5
Step-by-step explanation:
The check digit is the very last digit on the right, the one by itself
The relationship between the y-axis and the line connecting F to F′ is (c) They are perpendicular to each other.
<h3>How to determine the relationship?</h3>
When a triangle FIT is reflected over the y-axis, the image and the pre-image of the triangle would be at either sides of the y-axis.
This means that the points on the image and the pre-image of the triangle are perpendicular to each other
Hence, the relationship between the y-axis and the line connecting F to F′ is (c) They are perpendicular to each other.
