A line has a slope of -4/5. Which ordered pairs could be points on a line that is perpendicular to this line?

(5,4) & (8,-10)

Step-by-step explanation:

First step:

You can use any number you want for b (I used 4)

Make x=0

Make y=0

Subtract 4 from both sides

Divide both sides by

Second step:

In order to make a line perpendicular to another the slope of the second line will be the negative inverse of the first line. So   will be for the second line.

Then you just need to repeat the process in first step to get the intercepts. (Again I used a random number like -10 for b)
