If the function is #g(t) = -5t +1# and we're solving for #g(-1)#, that simply means we substitute #-1# for #t# into the function:

#g(-1) = -5(-1) +1#

and then solve:

#g(-1) = 5 +1#
#g(-1) = 6#

When simplifying, don't forget that a negative number multiplied by another negative equals a positive number, so #-5 * (-1)# equals positive #5#.
