Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined

What would the rule be for the reflection of y=-3

Does the construction demonstrate how to copy an angle correctly using technology a) yes the distance between points a and f was used to create circle h b) yes the distance between points f and g was used to create circle h c) no the distance between points a and f was used to create circle h d) no the distance between points f and g was used to create circle h
