What is the slope of the line that passes through (1, 4) and (1, -3)?
7, -7, Undefined, 0

Solution:

The slope formula has to be used to determine the slope of a line with two points given.

m = y₂ - y₁/ x₂ - x₁

Where m is the slope of the line

(x₁, y₁) and (x₂, y₂) are the two points of the line.

Now let us substitute (1, 4) and (1, -3) in the formula

m = (-3 - 4)/ (1 - 1)

m = -7/0

As the x coordinates of the lines are the same, the line is vertical and slope is undefined.

Therefore, the slope of the line is undefined.

What is the slope of the line that passes through (1, 4) and (1, -3)?
7, -7, Undefined, 0

Summary:

The slope of the line that passes through (1, 4) and (1, -3) is undefined.
