Perpendicular lines have slopes that are negative reciprocals to each other, that is, if one slope is a/b, the other is -b/a
in this case, the given slope is 1/3, so the other line's slope is -3/1, which is -3
from the graph we see that the y intercept of line b is -4, so the equation of line b is: y=-3x-4
Answer:
You can even correct mistakes when someone is protesting that whatever it is, is a good deal for price. If your ordering something and they demand more money you correct them because you can use math in your life. You can have more availability to jobs, it will be easier to find a job as an engineer.

It develops our reasoning, helps us to have analytical thinking, quickens our mind, generates practicality and also its use can be applied in the day to day. This is what it should include.
Answer:
check all that apply to what? I'm happy to help but I need the question
-4x+y=16
-5x-y=21
Subtract -5x-y=21 from -4x+y = 16
which leave x=-5
Then substitute -5 for x to get y. In the first equation .
