Answer:
y = -x + 1
Step-by-step explanation:
The equation of a line is: y = mx + c where m is the slope of the line and c is the y-intercept. I will be calculating the slope using the points (3, 0) and (0, 1).
Slope =
=
Thus, the slope of the line is -.
Based on the graph, the y-intercept is 1.
Thus, the equation of the line is: y = -x + 1.
Answer:
The exponential model is .
Step-by-step explanation:
The exponential model can be modelled by the following mathematical expression:
(1)
Where:
- Independent variable.
- Dependent variable.
- Coefficients.
If we know that and
, then we get the following system of equations:
(2)
(3)
If we divide (3) by (2), we calculate the value of :
And by (2), we determine the value of :
The exponential model is .
