8. What is the equation of the line that contains (2, 3) and is perpendicular to the line y = 2x + 3?
1 answer:
Hi there! :)
Given equation:
y = 2x + 3
A perpendicular line would have a slope of the negative reciprocal, therefore:
2x --> -1/2x
Use the equation y = mx + b to plug in the given point values along with the slope to solve for the final equation:
3 = -1/2(2) + b
3 = -1 + b
3 + 1 = b
b = 4
Therefore, the final equation is:
y = -1/2x + 4
The correct answer choice is C, y = -1/2x + 4.

Step-by-step explanation:
In a two tailed test the probability of occurrence is the total area under the critical range of values on both the sides of the curve (negative side and positive side)
Thus, the probability values for a two tailed test as compared to a one tailed test is given by the under given relation -
\
Here
Substituting the given value in above equation, we get -
