What is the slope of a line that has two points of...

(-1, 4) and (4, 4)

as always, ychange/xchange. In this case, 0/5 = 0

You can always plot the points. In this case, it would have been easy to see that the line between them was horizontal.
Of course, you would then have to remember that the slope of a horizontal line is zero, because y does not change ...

To find the slope of a line that passes through two points, you can use the formula:

slope = (change in y-coordinates)/(change in x-coordinates)

Let's call the coordinates of the first point (x1, y1) and the coordinates of the second point (x2, y2). In this case, the first point is (-1, 4) and the second point is (4, 4).

The change in y-coordinates is y2 - y1, which is 4 - 4 = 0.
The change in x-coordinates is x2 - x1, which is 4 - (-1) = 5.

Therefore, the slope is 0/5, which simplifies to 0.

So, the slope of the line passing through the points (-1, 4) and (4, 4) is 0.
