Question

what is the slope of the line that contains the points (4 -1) and (-1,4)

Answer 1

Answer:

-1

Step-by-step explanation:

The slope formula when given two points is

m = ( y2-y1)/(x2-x1)

    = (4 - -1)/(-1 -4)

    = (4+1)/(-5)

    = 5/-5

   =-1

Answer 2

Answer:

-1

Step-by-step explanation:

Use the equation for slope.

$m=\frac{y_{2}-y_{1} }{x_{2}- x_{1} }$

Plug in the given points into the equation.

$m=\frac{4-(-1) }{-1- 4 }\\m=\frac{4+1 }{-5 }\\m=\frac{5}{-5 }\\m=\frac{1}{-1 }\\m=-1$

The slope is -1.
