Question

Tell the slope of a line that contains the points (5,-3) and (7,3)

Answer 1

You can find the slope of a line by using the formula m = y_2 - y_1 / x_2 - x_1, where m is the slope and x and y are the given coordinates.

m = y_2 - y_1 / x_2 - x_1   Plug in the given coordinates
m = 3 - (-3) / 7 - 5               Cancel out the double negative
m = 3 + 3 / 7 - 5                  Add and subtract
m = 6 / 2                             Simplify
m = 3

The slope of the line is 3.

Answer 2

(5,-3)(7,3)
slope = (y2 - y1) / (x2 - x1)
slope = (3 - (-3) / (7 - 5) = (3 + 3) / 2 = 6/2 = 3 <==
