What is the slope of a line that is perpendicular to the graph of : y = -1/2x + 4?

y = -1/2x + 2
-1/2 * 2 = -1

So the slope is -1.

Let me know if this is right or wrong.

Thanks for the help.

NO INDEED.
The slope is 2.

Find the slope of the line given. Call it m.

The slope of the perpendicular line is -1/m.

Thank u alex and pka.

Do you understand now why the slope is 2, Dominic?

 

[Dominic]

Yes, thank you for asking.

did you use the formula x1/y1 - x2/y2 ??

 

[Guest]

did you use the formula x1/y1 - x2/y2 ??

Why would we?

well in math class last year i remember mr bradley my old math teacher for 8th grade saying to use that.

Use that when? You use whatever gets the job done.
