The coordinates of point 1 are 250 units of X and 40 units of Y. The coordinates of point 2 are 250 units of X and 70 units of Y. The slope of the line between points 1 and 2 is what?

Slope = Change in y / change in y

How much did y change between the two points?
How much did x change between the two points?

Divide them.

Whoops.

Slope = Change in y / change in x

To find the slope of a line between two points, we can use the formula:

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

In this case, point 1 has coordinates (250, 40) and point 2 has coordinates (250, 70).

The change in x is the difference between the x-coordinates, which is 250 - 250 = 0 units.
The change in y is the difference between the y-coordinates, which is 70 - 40 = 30 units.

Plugging these values into the formula:

slope = (30) / (0)

However, we have a problem here because division by zero is undefined.

In this case, since the change in x is zero, the line between these two points is a vertical line. A vertical line does not have a slope in the traditional sense since the slope represents the ratio of the vertical change to the horizontal change.
