Step-by-step explanation:
Let represent the number of monitors sold.
Given:
is the number of years since 1990.
So, for the year 1990, .
For the year 2000, 10 years passed. So, .
Now, monitors sold in 1990 are 150. So, at
Monitors sold in 2000 are 900. So, at
Thus, the two points are and
.
The slope of a line with points and
is given as:
Slope,
For the points and
, the slope is given as:
Slope,
Now, the y-intercept is the point where . So, the point
has
value as 0.
So, the y-intercept is 150.
Equation of a line in slope-intercept form is given as:
Where, is the slope and
is the y intercept.
Here, and
.
Therefore, the equation that represents the above data is given as:
