Find the slope of the line passing through the points (9,12) and (8,4.
equation for slope = y2-y1/x2-x1
To find the slope of the line passing through the points (9,12) and (8,4), we can use the slope formula:
slope = (y2 - y1) / (x2 - x1)
Using the given points, let (x1, y1) be (9, 12) and (x2, y2) be (8, 4). Substituting these values into the formula, we have:
slope = (4 - 12) / (8 - 9)
Simplifying further:
slope = (-8) / (-1)
Finally, simplifying the negative fraction:
slope = 8
Therefore, the slope of the line passing through the points (9,12) and (8,4) is 8.
To find the slope of a line passing through two given points (x1, y1) and (x2, y2), you can use the formula:
slope = (y2 - y1) / (x2 - x1)
Let's apply this formula to the given points (9, 12) and (8, 4):
x1 = 9, y1 = 12
x2 = 8, y2 = 4
Now substitute these values into the formula:
slope = (4 - 12) / (8 - 9)
Simplifying further:
slope = (-8) / (-1)
Dividing both the numerator and denominator by -1, we get:
slope = 8
Therefore, the slope of the line passing through the points (9, 12) and (8, 4) is 8.
