1/2, line rises

we are given the following pair of points and and we are to find the slope of line passing through these points:

(-1, 3) and (3, 5)

slope = \frac {y_2 - y_1} {x_2 - x_1} = \frac{5-3} {3--1} = \frac{2} {4} = \frac{1} {2}

the slope of this line is 1/2 which is positive so the line rises from bottom left towards top right.

Answer:

b. Positive psychology

Explanation:

Humanistic theories of personality have helped fuel research into character strengths, happiness, and thriving. In other words, the humanistic approach has aided in the growth of positive psychology.

A positive psychology can be defined as a broad range of science that typically deals with only the positive aspects of an individual's life. Thus, positive psychology is mainly centered around being happy, joyous, flourishing, thriving, character strength, well-being etc.

Hence, positive psychology reinforces positivity rather than negativity such as bitterness, sadness etc.

AveGali [126]

Answer:

Classical conditioning

Explanation:

In psychology, classical conditioning is a method of learning by pairing stimuli. Usually, first one stimulus causes a natural answer (the unconditioned stimulus causes an unconditioned answer), then this unconditioned stimulus is paired with another stimulus that doesn't cause an answer by itself  at first but after some repetitions, the new stimulus (conditioned stimulus) causes the same answer from the unconditioned stimulus and this answer becomes the conditioned answer.

In this example, pets have learned to pair the sound of the electric can opener with the arrival of their canned food so they have learned to respond to this sound and therefore, they run toward the sound of the can opener even if there is no cat food present. <u>The can opener would be the conditioned stimulus which has been paired with the food (unconditioned stimulus) and has created the response of the pets running toward this sound (Conditioned answer). </u>Therefore this is an example of classical conditioning.
