Answer:
The constant term represents the initial velocity of the object
Step-by-step explanation:
If we have an equation with the form:
y = a + bx
Where a is a constant term, we can identify a as the initial value of y or the value of y when x is equal to 0.
So, in this case, if the expression 15 + 5x represents the velocity of an object, we can say that the constant term 15 represents the initial velocity of the object or the velocity of the object at 0 seconds.
