The figure description helps; Choice A; by showing that a triangle cannot be formed when the sum of the lengths of two sides is less than the length of the third side.
<h3>What is the triangle inequality theorem?</h3>
The triangle inequalities theorem postulates that the sum of lengths of two sides of a triangle must be greater than the length of the third side.
On this note, it follows that the since the sum of sides given in the description 7 and 4 is less than 15, the segments cannot be used to form a triangle.

The equation in slope-intercept form is: 
Step-by-step explanation:
The equation of a straight line in slope-intercept form is given by:

Here m is the slope of the line and b is the y-intercept
Given
m = 5
and
Point (1,9)
Putting m=5 in the slope-intercept form of line

To find the y-intercept, putting the given point in the equation

Put the value of y-intercept in the equation

Hence,
