Given the table below, find the slope.
Understand the Problem
The question is asking to find the slope between two points given in the table, where x and y coordinates are provided. The slope can be calculated using the formula (y2 - y1) / (x2 - x1).
Answer
The slope is $-1$.
Answer for screen readers
The slope between the two points is $-1$.
Steps to Solve
- Identify the Points
From the table, the points are:
- Point 1: $(x_1, y_1) = (8, 0)$
- Point 2: $(x_2, y_2) = (7, 1)$
- Use the Slope Formula
The slope $m$ between two points is calculated using the formula:
$$ m = \frac{y_2 - y_1}{x_2 - x_1} $$
Substituting the values of the points into the formula:
$$ m = \frac{1 - 0}{7 - 8} $$
- Calculate the Slope
Now perform the calculations:
$$ m = \frac{1}{-1} $$
- Final Result
Calculating the above gives:
$$ m = -1 $$
The slope between the two points is $-1$.
More Information
The slope represents the rate of change between the two points and indicates that for each unit increase in the x-direction, the y-value decreases by 1 unit.
Tips
- Mixing up the coordinates: Always double-check that $x_1$ and $y_1$ correspond to the same point, as well as $x_2$ and $y_2$.
- Forgetting to subtract in the correct order for $y$ and $x$, which can lead to incorrect slope calculations.
