Answer 1

The equation that shows the relationship between the number of students photographed, x, and the total number of pictures on the memory card, y, can be expressed as:

y = x + 2

The first two pictures she took to check that everything is working properly, so the total number of pictures she expects to take will be the number of students photographed (x) plus the two test pictures.
