Question

a school photographer just bought a new memory card for her camera. she took 2 pictures to check that everything is working properly. now that its picture day, she expects to take 1 picture of each student. write an equation that shows the relationship between the number of students photographed, x, and the total number of pictures on the memory card, y. y =

Explanation:

Step1: Identify the fixed and variable parts

The photographer already took 2 pictures (fixed), and for each student \( x \), she takes 1 picture (variable part, which is \( 1\times x = x \)).

Step2: Form the equation

The total number of pictures \( y \) is the sum of the fixed pictures and the pictures taken of students. So \( y = x + 2 \).

Answer:

\( y = x + 2 \)
