Respuesta :
slope = (y2 - y1) / (x2 - x1)
(2,-1)(0,4)
slope = (4 - (-1) / (0 - 2) = (4 + 1) / -2 = 5/-2 = -5/2
(2,-1)(0,4)
slope = (4 - (-1) / (0 - 2) = (4 + 1) / -2 = 5/-2 = -5/2
Answer: The correct option is (D) [tex]-\dfrac{5}{2}.[/tex]
Step-by-step explanation: We are given to find the slope of the line that contain the points x(2, -1) and y(0, 4).
We know that
the slope of a line that contain the points (a, b) and (c, d) is given by
[tex]m=\dfrac{d-b}{c-a}.[/tex]
Therefore, the slope of the given line will be
[tex]m=\dfrac{4-(-1)}{0-2}=\dfrac{4+1}{-2}=-\dfrac{5}{2}.[/tex]
Thus, the slope of the given line is [tex]-\dfrac{5}{2}.[/tex]
Option (D) is CORRECT.
