What’s the slope of a line perpendicular to a line through points,
e(5,7), f(3,1)

-1/3 is the slope perpendicular

Step-by-step explanation:

When we have 2 points, we can use the formula

m = (y2-y1)/(x2-x1) to find the slope

m = (1-7)/(3-5)

   =-6/-2

    =3

The slope is 3

We want a slope perpendicular

Remember that is the negative reciprocal

- (1/3)

-1/3

Two lines are perpendicular when,

Now solve for to get

First we calculate the slope from the given points .

Now use the first formula and insert the data in it to find the value of the second slope ,

And that's it.

Hope this helps.
