Find the slope of the line containing each given pair of points, If the slope is undefined, state this (-1,4) and (5,-8)
Use the slope formula.
m = (y2 - y1)/(x2 - x1)
m = (-8 - 4)/[5 - (-1)]
Solve.
To find the slope of a line passing through two points, you can use the slope formula:
m = (y2 - y1) / (x2 - x1)
Given the points (-1, 4) and (5, -8), we can assign the values as follows:
x1 = -1
y1 = 4
x2 = 5
y2 = -8
Now, substitute the values into the slope formula:
m = (-8 - 4) / (5 - (-1))
Simplifying further:
m = (-12) / (5 + 1)
m = -12 / 6
m = -2
Therefore, the slope of the line passing through the points (-1, 4) and (5, -8) is -2.
