Equation of a line:
The equation of a line has the following format:
In which m is the slope.
Finding the slope of a line, given two points:
When we are given two points of a line, the slope of the line is given by the change in y divided by the change in x.
Points (4,r), (r,3)
Change in y: 3 - r
Change in x: r - 4
Slope is 0, so:
The value is r = 3.
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x ----> the number of days
y ----> the amount of money in her bank account
we know that
The equation of the line in slope intercept form is equal to
where
m is the slope or rate
b is the y-intercept or initial value
In this problem we have
The slope is equal to
----> is negative because is a decreasing function
----> initial amount in the account bank
substitute
see the attached figure to better understand the problem
