Graph the function f(x)=3/5x-5
1 answer:
Answer:
see the graph below
Step-by-step explanation:
The equation is given in slope-intercept form, so you immediately know one point—the y-intercept: (0, -5).
Another point can be determined from the slope of 3/5, which tells you the line goes up 3 units for each 5 units to the right. Adding 5 to x and 3 to y of the y-intercept, the point we get is (5, -2).
The graphing program I have does not have a "line tool", but it shows the given equation plots a line through those points.

Step-by-step explanation:
1) Solving Part A (we need to find the slope):
- The slope is
-->
,
,
, and
are all values from the table. We know that the left column is the x-values, and the right column is the y-values as that is the conventional way of depicting them.
2) Using the y-values of 1150 and 1090, and their corresponding x-values (5 and 10 respectively), we can get the slope:
- ==>
==>
==>
, so the slope is -12.

1) Part B (analysis)
We can see that no matter what 2 y-values and their corresponding x values we use, the slope always is the same. This means that the rate of change is constant.
