Question

3. Calculate the slope of a line passing through the points (- 2, 4), (- 1, 1) , and (1, - 5)

Answer 1

Answer:

-3

Step-by-step explanation:

m = (y2 - y1)/(x2 - x1)

To find the slope we need to use 2 points.

For example,

(- 2, 4), (- 1, 1)

m = (4 - 1)/(- 2-(-1)) = 3/(-1) = -3

or

(- 1, 1) , and (1, - 5)

m = (1-(-5))/(-1-1)= 6/-2 = -3

So, if we have a line , we can use any 2 points to find the slope.
