Answer:
-0.25
Explanation:
xD im a bit late :P
we can pick any 2 points on the line.
let's pick, (-1, 2) and (-3, 1)
Alright, so the formula to calculate slope is in the attachment below.
If you're a bit confused on what the little 2 and 1 at the bottom of each of those numbers are representing the points. So let's say (-3, 1) is point 2. And (-1, 2) is point 1.
the variable "y" is the y-coordinate.
the variable "x" is the x-coordinate.
And all we need to do now is just sub in the values and that's your answer.
so we have the 2 y-coordinates, 1 and 2.
We subtract them. 1-2=-1
then we have the 2 x-coordinates, -1, -3
-1-3=-4
so -1/-4 is -0.25
I am not sure if this is right -___- but this is what I've been taught sooooo :?
