Question

Find the slope of the line through (4,−5) and (−2,1).

Answer 1

Answer:

-1

Step-by-step explanation:

To find the slope, plug the values of x and y into the slope formula.

y2 - y1 / x2 - x1

1 - (-5) / - 2 - 4

6 / -6

= -1

Answer 2

Answer:

slope = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (4, - 5) and (x₂, y₂ ) = (- 2, 1)

m = $\frac{1+5}{-2-4}$ = $\frac{6}{-6}$ = - 1
