Question

A line passes through the points A(-1,7) and B(1,3)find the slope​

Answer 1

Answer:

-2

Step-by-step explanation:

The slope of a line is given by

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

    = (3 - 7)/(1 - -1)

    = (3-7)/(1+1)

    = -4/2

   -2

Answer 2

Answer:

-2

Step-by-step explanation:

Use the slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{3-7}{1-(-1)} =\frac{-4}{2} =-\frac{4}{2} =-2$

The slope of the line should be -2.
