Let the time for jogging be on y axis and number of weeks be on x axis.
Express the general equation of the line,
y=mx+c.
Here, m is slope and c is y intersept.
Given that, you start by jogging for 14 minutes each day. So, c is 14.
Also, given that you increase your jogging time by 7 minutes implies,
m=7.
Therefore, the equation is,
