Answer:
see below
Explanation:
Slope: The slope is
, and this means that depending on how many students are increased, then the total number of flags also increases.
Y-intercept: When x=0, when there are 0 students, how many flags are already made.
The slope is


The y intercept is (0,8)
In this context, the slope represents that for every 3 students, 1 flag string is made. The y-intercept represents that when no students had made their own flag string, 8 flag strings had already been pre-made.
To answer the very last question (even though you didn't ask for it), the equation would be:
y=3x+8
