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

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
