Math Problem Statement
Graph the function y = (4/3)x - 1 using the given table of x-values and fill in the missing y-values.
Solution
To graph the given function and complete the missing table values, let’s proceed step by step.
The equation of the line:
Here:
- The slope ,
- The y-intercept .
1. Fill in the missing -values in the table:
To calculate -values, substitute -values into the equation .
- When :
- When :
- When :
- When :
2. The completed table:
-3 | -5 |
0 | -1 |
3 | 3 |
6 | 7 |
3. Plot the points:
Plot the following points on the graph:
These points should form a straight line because the equation is linear.
4. Draw the line:
- Start at the y-intercept ,
- Use the slope : move 4 units up and 3 units to the right to plot additional points.
