Explanation:
the picture is very blurry.
I understand we need the y-intercept in every case and then move the pictures into the empty frames based on sorting these numbers from lowest to highest.
the y-intercept is the point, where a function/curve intersects the y-axis.
in other words, it is the y-value of the point, where x = 0.
so,
1. 0
2. -6
3. looks like -2 (again, very blurry)
4. looks like +2
5. +6
6. +4
sorting these gives us
2. -6 3. -2 1. 0 4. +2 6. +4 5. +6
therefore the 6 frames need to receive the original pictures in that sequence.
