<u>ANSWER: </u>
If two points on line l above have coordinates (0, A) and (2, −3), then the value of A is -1
<u>SOLUTION:</u>
Given, two points on line l have coordinates (0, A) and (2, −3),
And the slope of the line is A,
We need to find a value.
We know that, slope of a line on which (x1, y1) and (x2, y2) are two points is given by
Here,in our problem,
now, substitute the values in formula we get
2A = -3 –A
2A+ A = -3
3A = -3
A = -1
Hence, the value of A is -1.
Answer:
y = x³ +2x² +x -1
Step-by-step explanation:
The attachment shows the four points we can read from the graph and the cubic regression function that fits them.
y = x³ +2x² +x -1

<em>Additional comment</em>
It is useful to become familiar with the regression function capability of your graphing calculator or spreadsheet. Free or inexpensive apps are available for tablet or phone, and on the web.
