Math Problem Statement
Solution
To find the linear equation that gives the rule for the table, we need to calculate the slope and then determine the y-intercept.
The table provided shows:
x | y |
---|---|
3 | 58 |
4 | 65 |
5 | 72 |
6 | 79 |
Step 1: Find the Slope (m)
The slope of a line is calculated using the formula:
Let's use the points (3, 58) and (4, 65):
The slope is .
Step 2: Find the Y-intercept (b)
The slope-intercept form of a linear equation is:
Now, using the point (3, 58) and the slope , we substitute into the equation to find :
Final Equation:
Thus, the equation of the line is:
You can enter this equation as the answer.
