What is the slop of the line contains points (1,1) and (5,-5) write a answer as friction as simplest from (hint 2/1 should be si

lozanna [386]

Answer:

$-\frac{3}{2}$

Step-by-step explanation:

Given parameters:

Points = (1,1) and (5,-5)

Unknown:

Slope = ?

Solution:

The slope of the a line is the ratio of the rise of a line to its run.

Slope = $\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

x1 = 1

y1 = 1

x2 = 5

y2 = -5

Insert the parameters and solve;

Slope = $\frac{-5 - 1}{5-1}$ = $\frac{-6}{4}$ = $-\frac{3}{2}$
