What is the slope of the line passing through the points (–1, 3) and (4, –7)?
A. 2


B. 3/4


C. -4/3


D. -2


Sagot :

the answer is a.2 because this coordinate is the only one along the slope

[tex]slope=\frac{y_2-y_1}{x_2-x_1}\\\\ (x_1,y_1)=(-1,3)\\ (x_2,y_2)=(4,-7)\\\\ slope=\frac{-7-3}{4+1}=\frac{-10}{5}=-2\\\\ Slope\ is\ equal\ to\ -2.\\Answer\ is\ D. [/tex]
