Given :
A line 2x + 1 =0 .
To Find :
The slope of the given line .
Solution :
We know , slope of line is given by the tangent of the angle between the x-axis and the line .
Now, for line 2x + 1 =0 i.e
.
The line is perpendicular to x-axis and cuts the x-axis at
.
Therefore , the angle between the line and x-axis is
.
So , slope
i.e undefined .
Therefore , the slope of given line is not defined .
Hence , this is the required solution .

Answer:
52.9°
Step-by-step explanation:
step 1
we know that
The total number of successful United States space launches that happened in the years 1957-1995 is equal to

step 2
The numbers of successful United States space launches that happened in the years 1980-1989 is equal to

step 3
The percentage of successful United States space launches that happened in the years 1980-1989 is equal to

step 4
Find out the measure of the central angle you would draw in a circle graph to represent the number of successful United States space launches that happened in the years 1980-1989
we know that
In a circle, 360 degrees represent the 100%
so
using proportion
Find out the measure of the central angle by a percentage of 14.68%
