a.
To write: an equation of a line using point (-2, -3).
a.
Answer to Problem 3P
Explanation of Solution
Given information: an equation in the last step of above example is given as follows-
We have to write an equation using point (-2, -3) instead of (1, 4).
b.
To write: the equations in slope intercept form and compare them.
b.
Answer to Problem 3P
Explanation of Solution
Given information: an equation in the last step of above example is given as follows-
An equation in the last step of above example is given as follows-
This is the required equation in slope intercept form.
Now the equation obtained in part a is as follows-
Here the both equations are same.
The point (-2, -3) already lies on the line in last step above example.
We can conclude that we can use any point on a line to write an equation of the line in point slope form.
