Question

The slope of a line that is perpendicular to a line whose slope is -2/7 is

-2/7
-7/2
7/2

Answer 1

The answer is 7/2. Hope this helps

Answer 2

Answer: 7/2

Explanation:

Since we know that the property of perpendicular lines says that the product of slopes of two perpendicular line is -1 .

Let m be the slope of line which is perpendicular to the line with slope
`(-2)/(7)`

Therefore by the property of perpendicular lines we have

`m*(-2)/(7)=-1\\\\\Rightarrow\ m=(7)/(2)`

Hence , the The slope of a line that is perpendicular to a line whose slope is -2/7 is 7/2.
