What’s the rate of change from 1,3?

it has the same slope and a different y-intercept

hope this : )

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
