how do i find the slope of line AB if A`s coordinates are(-4,3) and B`s coordinates are (2,-1)
A(-4,3) and B(2,-1)
If you have points A(x1,y1) and B(x2,y2)
Slope m = (y2 - y1)/(x2 - x1)
so i just have to do (-1-3)/(3-(-4)
m = (-1-3)/(2-(-4)
You had 3, should be 2
To find the slope of a line AB, you can use the formula:
slope = (change in y-coordinates) / (change in x-coordinates)
In this case, point A has coordinates (-4, 3) and point B has coordinates (2, -1).
To calculate the change in y-coordinates, you subtract the y-coordinate of point A from the y-coordinate of point B:
change in y-coordinates = -1 - 3 = -4
To calculate the change in x-coordinates, you subtract the x-coordinate of point A from the x-coordinate of point B:
change in x-coordinates = 2 - (-4) = 6
Now you can use the formula to find the slope:
slope = (-4) / 6 = -2/3
Therefore, the slope of the line AB is -2/3.
