Which type of validity applies to research results based on subjective qualities?

Semenov [28]

The answer is concurrent validity.

This kind of validity is based on comparing the results with a measure that has been validated previously.

It is used in more subjective qualities given that they cannot be measured with instruments but it is more an appreciation that depends on the subject that performs the test.

You want to find the equation for a line that passes through the point (3,-4) and has a slope of -1/2.

Mashcka [7]

Answer:

$y = -\frac{1}{2}x -\frac{5}{2}$

Step-by-step explanation:

We are given;

A point where the line is passing through as (3, -4)
The slope of the line -1/2

We are required to determine the equation of the line;

Note that, one way we can get the equation of a straight line is when we are given a point where the line is passing through and its slope.
Thus, in this case, we can determine the equation;

Taking another point (x, y)

Then; (x, y) , ( 3, -4) and slope -1/2 can give us the equation;

That is;

$\frac{y+4}{x-3}=-\frac{1}{2}$
