Which of the following is true of (1, 4) and (1, −7)?

More information is needed to determine the relationship between the two points.

The points lie on a diagonal line.

The points lie on a vertical line.

The points lie on a horizontal line.

The points lie on a vertical line.

Step-by-step explanation:

The x-values in the given two points are the same. If they were graphed and then connected, it would form a vertical line.

[see graph]

So, the points would lie on a vertical line.

answer: the answer is 127 degrees

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
