what is the slope of the line (4,9) and (2,9)?
actually, you mean the line joining the two points.
well, starting at (4,9), how much do x and y change getting to (2,9)?
y does not change, so the slope is zero.
thanks :)
To find the slope of a line, you can use the formula:
slope = (change in y-coordinates) / (change in x-coordinates)
Let's apply this formula to the given points (4,9) and (2,9).
First, let's determine the change in y-coordinates:
Δy = 9 - 9 = 0
Next, let's determine the change in x-coordinates:
Δx = 4 - 2 = 2
Now we can calculate the slope using the formula:
slope = (change in y-coordinates) / (change in x-coordinates)
slope = 0 / 2
Since the change in y-coordinates is 0, the slope of the line will be 0.
Therefore, the slope of the line passing through the points (4,9) and (2,9) is 0.
