Which characteristics will prove that δdef is a right, isosceles triangle? segment de is larger than segment ef, and their slopes are the same. segment de is larger than segment ef, and their slopes are opposite reciprocals. the lengths of segment de and segment ef are congruent, and their slopes are the same. the lengths of segment de and segment ef are congruent, and their slopes are opposite reciprocals.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

- (2, -7)

- lines r and s and lines t and u must be parallel
