4. Subtract the x-coordinates to find the horizontal distance between the points

a) (-3, 0) and (1, 0)
b) (5,0) and (-2, 0)
c) (-1, -10) and (1,-10)
d) (-8, 6) and (-2, 6)

a) (-3, 0) and (1, 0):

1 - (-3) = 4

The horizontal distance between the points is 4.

b) (5,0) and (-2, 0):

-2 - 5 = -7

The horizontal distance between the points is 7 (but negative because the second point is to the left of the first point).

c) (-1, -10) and (1,-10):

1 - (-1) = 2

The horizontal distance between the points is 2.

d) (-8, 6) and (-2, 6):

-2 - (-8) = 6

The horizontal distance between the points is 6.

a) (-3, 0) and (1, 0): The x-coordinates are -3 and 1. Subtracting -3 from 1 gives us 1 - (-3) = 1 + 3 = 4. The horizontal distance between the two points is 4.

b) (5, 0) and (-2, 0): The x-coordinates are 5 and -2. Subtracting 5 from -2 gives us -2 - 5 = -7. The horizontal distance between the two points is -7.

c) (-1, -10) and (1, -10): The x-coordinates are -1 and 1. Subtracting -1 from 1 gives us 1 - (-1) = 1 + 1 = 2. The horizontal distance between the two points is 2.

d) (-8, 6) and (-2, 6): The x-coordinates are -8 and -2. Subtracting -8 from -2 gives us -2 - (-8) = -2 + 8 = 6. The horizontal distance between the two points is 6.
