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.
Answer:
y = 1/2x + 5/2
P.S, this isn't geometry really. It's more like algebra :)
Step-by-step explanation:
Step 1: Find equation of line AB
m = (5 - 1)/(-2 - 0)
m = 4/-2
m = -2
y = -2x + 1
Step 2: Find slope of perpendicular line
<em>Take the negative reciprocal of line AB</em>
m = 1/2
y = 1/2x + b
Step 3: Find <em>b</em>
6 = 1/2(7) + b
6 = 7/2 + b
b = 5/2
Step 4: Rewrite perpendicular equation
y = 1/2x + 5/2
or
y = 0.5x + 2.5
