Step-by-step explanation:
to figure out b we can consider the following formula:
the form of vertex coordinate given by
so according to the question
by order pair we obtain:
now substitute the value of h and a to the formula:
simplify multiplication:
cross multiplication:
divide both sides by -1:
now we need to figure out C to do so substitute -7 for x and -5 for y which yields:
simplify square:
simplify multiplication:
simplify addition:
cancel 49 from both sides:
hence,
- b=-14
- C=-54
