The Pythagorean Theorem. Consider the right triangle including the two points and a third point having the same x coordinate as one and the same y coordinate as the other. Apply the Pythagorean theorem.
For (x1, y1) and (x2,y2): dist. = sqrt((x1-x2)2 + (y1-y2)2)
When a line segment connecting two points is horizontal the length of the segment can be found by finding the absolute value of the difference in x-coordinates of the two points.
The slope of a line is the rise divided by the run. In other terms, if, X = the horizontal distance between two points on a line and Y = the vertical distance between the same points, then m = Y/X

If you know the end points then use the distance formula or simply use a ruler.
True
Horizontal

Add the x-coordinates of the points and take the absolute value

It is used, except that, because one set of coordinates are the same, the formula collapses into a simpler form.

how do you find distance between points
Subtract the x-coordinates of the points and take the absolute value. Using the Pythagorean Theorem, the y-value would be zero, and the distance the square root of its own square.
The distance between the points of (4, 3) and (0, 3) is 4 units
The answer will be the diagonal (hypotenuse) for a horizontal distance x2-x1 (-6) and a vertical distance y2-y1 (8). The square root of the squares is sqrt [62 + 82] = sqrt [100] = 10.
