Answer:
k = 7d
Step-by-step explanation:
y = mx + b
slope (m): 7 kilometers each day
x: Brian runs over d days
y - intercept (b): when x = 0, y = 0 since it will be day 0
y: total kilometers, k
Answer:
k = 7d
Step-by-step explanation:
The standard form of an equation is :
y = mx + b
Here, the variables for y and x are k and d respectively.
===============================================================
It is given that Brian runs 7 kilometers each day. Hence, that is our rate of change, m. The value of b will be 0 as he starts from 0 km.
============================================================
So, the equation is :
k = 7d
