I can’t quite see the question. Mind taking a picture of it closer?
Answer:
Step-by-step explanation:
12t2 - 6t
Initial speed of the skateboard (u) = 0 m/s (Starts from rest)
Acceleration of the skateboard (a) = 2 m/s²
Time taken by the skateboard (t) = 2s
By using equation of motion, we get:

Final speed of the skateboard(v) = 4 m/s
The y-intercept is "equal to", "y=1", "x=0".
_____
The y-intercept is the "+1" part of the equation y=2x+1.
