Answer:

Step-by-step explanation:
Let us assume that,
number of minutes read by Kiran is = x minutes.
number of minutes read by Andre is = y minutes.
Andre read for 58 minute more than that of Kiran.
Converting minute to hour we get,



So the relationship between x and y will be,

F(-7) = 2x + 8,
f(-7) = 2(-7) + 8,
f(-7) = -14 + 8,
f(-7) = -6
Hope this helps you out, I didn't know if there was a plus sign between 2x and 8 but hope this helps you out!
