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,
