The answer is D
Step-by-step explanation:
Answer:
The slope of the line is
and the equation of the line is
.
Step-by-step explanation:
From table we understand that slope of the line is constant, that is, for each change of
there is one and only change in
, fulfilling the main characteristic of a line and we can determine the slope for every point of the line by means of the following expression:
(1)
Where:
- Initial and final x-coordinates of the line.
- Initial and final y-coordinates of the line.
If we know that
and
, then the slope of the line is:


From graph we conclude that x-intercept of the line is
. Hence, the equation of the line is
and we proceed to plot the expression with the help of a graphing tool.
Step-by-step explanation:
In this question we need to decrease 216 by
or 37.5 %.
For this, firstly find 37.5 % of 216.

Now subtracting 81 from 216 to find decrease of 216 by 37.5 %.
So,
216-81 = 135
Hence, 135 is the decrease of 216 by 37.5 %.
