Question

What is the slope of this line?
-4,2 -1,2

Answer 1

To find the slope of a line given two points \((x_1, y_1)\) and \((x_2, y_2)\), you can use the slope formula:

\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]

Given the points \((-4, 2)\) and \((-1, 2)\):

- \(x_1 = -4\), \(y_1 = 2\)
- \(x_2 = -1\), \(y_2 = 2\)

Now, substitute the values into the formula:

\[
m = \frac{2 - 2}{-1 - (-4)}
\]

This simplifies to:

\[
m = \frac{0}{-1 + 4} = \frac{0}{3} = 0
\]

The slope of the line is \(0\), which indicates that the line is horizontal.
