Answer:
Step-by-step explanation:
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points J(1, -4) and K(-2, 8).
Substitute:
[tex]m=\dfrac{8-(-4)}{-2-1}=\dfrac{8+4}{-3}=\dfrac{12}{-3}=-4[/tex]
The slope of JK is -4 if the two points located on JK are (1,-4) and k(-2,8) after applying the slope formula.
A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have two points located on JK are (1,-4) and k(-2,8).
The slope can be found:
[tex]\rm m =\dfrac{8-(-4)}{-2-1}[/tex]
m = 12/(-3)
m = -4
Thus, the slope of JK is -4 if the two points located on JK are (1,-4) and k(-2,8) after applying the slope formula.
