Answer: Yes it is
Explanation:
A linear relationship simply put, is a relationship between variables that when constructed, forms a straight line. This happens when y changes at a constant rate if x changes by a constant rate as well for instance, 1.
From this question, assume x is minutes and y is the total number of pieces put together. This means that every time x (minutes) increases by 1, y increases by 5 pieces.
The formula would look like this;
y = 5x + 253
This is a formula for a straight line so indeed, this relationship is linear.
