Math help please what is the line grsph

So you need to find the slope that is perpendicular to equation.

Line L: y = 3x + 5

For it to be perpendicular, the slope has to be the opposite of 3 in 3x.

Since it is a positive value, we need to change it into a negative value in order for it to be opposite (perpendicular). So that will be -3.

Now we have to flip it. There is a 1 under that -3, it’s just not necessarily shown. So you flip it upside down and that will be -1/3.

-3/1 —> -1/3

The answer is -1/3.
