What is the slope of a triangle - Graph and classify

Question

A(3,-5), B(7,1),C(3,1)

 

Given info

 

Slope AC = undefined

slope BC =0

distance of BC =4

 

 

Slope AB= ?

distance AC= 6 ( marked correct on my test)

distance AB=?

Answer 1

For any two points (x₁,y₁) and (x₂,y₂):

• Slope = (y₂-y₁)/(x₂-x₁)
• Distance = √(y₂-y₁)²+(x₂-x₁)²

Your points are:

• A = (3,-5)
• B = (7,1)
• C = (3,1)

 

Plug the points into the formulas to get your answers.  Click on the link below to view the graph:
