PLZZ HELP 20 POINTS AND BRAINLIEST TIMED TEST!!!

What is the slope of a trend line that passes through the points (5, 80) and (7, 65)?

A. - 15/2
B. - 2/15
C. 2/15
D. 15/2

Respuesta :

Answer:

A

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (5, 80) and (x₂, y₂ ) = (7, 65)

m = [tex]\frac{65-80}{7-5}[/tex] = [tex]\frac{-15}{2}[/tex] = - [tex]\frac{15}{2}[/tex]

Answer:

A or -15/2

Step-by-step explanation:

Slope is measured my y₂ - y₁ divided by x₂ - x₁.

65 - 80 / 7 - 5 =

-15 / 2
