Can you determine any purpose why these concepts are present in the pictures?
puteri [66]

The purpose why these concepts are present in the pictures is to develop imagination power among students.

As you imagine more, your mind becomes stronger and you have greater mental control. Innovation requires a strong imagination. If you succeed in what you set out to do, the same individuals who now accuse you of daydreaming will begin to aspire to be like you. Keep your aspirations high and your imagination expanding.

Imagination is a potent brain stimulant because it forces you to think differently than most people do. Your imagination can help you come up with scenarios that most effectively handle difficulties, even though your brain might classify them as being unexpected.

What is the slope of the line that passes through the points (4.2) and (-16, -10)?
sergij07 [2.7K]

Given:

A line passes through the points (4,2) and (-16, -10).

To find:

The slope of the line.

Solution:

Slope Formula:

m=\dfrac{y_2-y_1}{x_2-x_1}

A line passes through the points (4,2) and (-16, -10). So, slope of the line is

m=\dfrac{-10-2}{-16-4}

m=\dfrac{-12}{-20}

m=\dfrac{3}{5}

Therefore, the slope of the line is \dfrac{3}{5}.
