Answer: -2
Explanation:
Our task is to find the slope of a line perpendicular to the line y = 1/2x + 3.
Main Idea :
If two lines are perpendicular, their slopes are negative reciprocals of each other.
----------------------------------------------------------------------------------------------------------
So, in order to determine the slope of the line that's perpendicular to y = 1/2x + 3, we need to follow these steps:
- Identify the slope of y = 1/2x + 3 (It's the number before x, so it's 1/2)
- Find the negative reciprocal of 1/2.
----------------------------------------------------------------------------------------------------------
The negative reciprocal of 1/2 is -2. Therefore, that's the slope.
