Math Problem Statement
Solution
To write the linear equation that represents the data in the table, we need to determine the relationship between and . Here's the table provided:
5 | -22 |
6 | -34 |
7 | -46 |
8 | -58 |
Step 1: Find the slope (rate of change)
The formula for the slope () between two points and is:
Using the points and :
So, the slope is .
Step 2: Find the y-intercept ()
The general form of a linear equation is: We can use one of the points, say , and the slope to solve for .
Step 3: Write the equation
Now that we have and , the equation is:
Thus, the linear equation that gives the rule for this table is:
Would you like any further details or clarifications?
Here are five related questions to deepen your understanding:
- How would the equation change if the slope were positive instead of negative?
- How can you check if a set of points follows a linear pattern using a graph?
- What does the slope of a line represent in real-world scenarios?
- How can you determine the y-intercept just by looking at a graph?
- What is the significance of the y-intercept in different types of linear equations?
Tip: When writing a linear equation, always verify both the slope and y-intercept by substituting a point from the table back into the equation.
