Find the slope of a line perpendicular to a line through the given points.
e(5, 7),f(3, 1)
-3
-1/3
1/3

Step-by-step explanation:

The slope of a line passing through two points (a,b) and (c,d) is given by :-

The given points : E(5, 7) and F(3, 1)

Then , the slope of a line passing through two points E(5, 7) and F(3, 1) is given by :-

We know that the product of slopes of two lines is -1.

Then , the slope of the line perpendicular to the line passing through the given points will be :-

Hence, the slope of the line perpendicular to the line passing through the given points =

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
