I'm afraid the answer is "No"
A variant of this question has already been asked here:
Paladin/Warlock sharing spell slots
The short version is you can't use a 1st level spell slot to cast a higher-level spell and as a 1st level warlock, the pact magic ability only gives you one slot of 1st level.
If you have both the Spellcasting class feature and the Pact Magic
class feature from the warlock class, you can use the spell slots you
gain from the Pact Magic feature to cast spells you know or have
prepared from classes with the Spellcasting class feature, and you can
use the spell slots you gain from the Spellcasting class feature to
cast warlock spells you know. (PHB, p. 164)
You still have to follow the rules for spellcasting though.
All of your warlock spell slots are of the same level.
The Warlock table shows how many spell slots you have. The table also
shows what the level of those slots is; all of your spell slots are
the same level. (PHB, p. 107)
