Answer:

k = 7d

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

Answer:

k = 7d

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
