Answer:
y = x + 4
Step-by-step explanation:
It is helpful to remember that parallel lines have the same slope. That is, the only thing different in the equation you write will be the added constant, the y-intercept.
If we call that constant "b", then we have ...
y = x + b . . . . . given equation with 8 replaced by b
2 = -2 + b . . . . with (-2, 2) filled in for (x, y)
4 = b . . . . . . add 2 to both sides
Then your parallel line has the equation ...
y = x + 4

Answer:
For the first 30 minutes, we will have a line with a given steepness, this will represent the 30 minutes riding at a fast pace.
Then he stops for 20 minutes, we will represent this with a constant line.
Then he again moves for another 30 minutes, but with a slower pace than in the first 30 minutes, then this line will be less steep than the first line.
A sketch of this situation can be seen below.
