Question

What is the slope of the line contaning (-1,5) and (2,-4)

Answer 1

Answer:

Slope=-3

Step-by-step explanation:

The formula used for slope is y2-y1/x2-x1

So -4-5/2 (-1) = -9/3= -3

Answer 2

Answer:

$\frac{-9}{3}$  

Simplified: -3

Step-by-step explanation:

So here we will do rise over run which is $\frac{y_2-y_1}{x_2-x_1}$

So here we have the points (-1,5) and (2,-4), lets plug these in!

$\frac{-4-5}{2-(-1)}$

Since we are subtracting a negative from a positive it would be simpler and a lot better if we were to turn that into $\frac{-4-5}{2+1}$

Now we do the equations!

-4-5= -9

2+1=3

Plug these in! Note that since the nine is negative, the whole thing will be!

$\frac{-9}{3}$

Simplify:

-3
