(5,25) (0,40) y=3(x)=b how do you find the slope of this equation

Question

(5,25) (0,40) y=3(x)=b 

 

find the slope

Answer 1

Hi Nana;

I am assuming that...

y=3(x)=b

is

y=3x-b

Henceforth, the slope is 3.

 

I am assuming that...

(5,25) (0,40)

are coordinates, (x,y)

 

Slope=(y_2- y₁)/(x₂ - x₁)

Slope=(40-25)/(0-5)

Slope=15/-5

Slope=-3

 

Please recheck the equation...

y=3(x)=b

should indicate the slope as -3, not 3.
