Find the slope of the line that passes through the points (1, 7) and (3, 3).

Slope of the line that passes through the points (1, 7) and (3, 3) = -2

Step-by-step explanation:

Given in the question two co-ordinates,

(1, 7)

(3, 3)

here x1 = 1

        x2 = 3

        y1 = 7

        y2 = 3

Formula to use

m =

   =

   = -4/2

  = -2

The slope of given line is -2

Step-by-step explanation:

Points to remember

Let (x₁, y₁) and (x₂, y₂) be the two points in a line, then the slope of the line is given by,

slope, m = (y₂ - y₁)/(x₂ - x₁)

To find the slope of given line

Here (x₁, y₁) = (1, 7) and (x₂, y₂) = (3,3)

Slope m =  (y₂ - y₁)/(x₂ - x₁) = (3 - 7)/(3 - 1)

= -4/2 = -2

Therefore the slope of given line is -2

step-by-step explanation:

ddd

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
