Use the image to answer the question.

An illustration shows a coordinate plane with four quadrants. The x and y axes extend from negative 10 to 10 in increments of 1. Two points are plotted on the graph. An upward slanting line connects the two points. Point A is plotted at coordinates left parenthesis negative 4 comma 1 right parenthesis. Point B is plotted at left parenthesis 3 comma 3 right parenthesis.

Determine the slope of the line.

Answer 1

To find the slope (m) of the line connecting the two points A \((-4, 1)\) and B \((3, 3)\), we can use the slope formula:

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

Here, we can assign:
- \( (x_1, y_1) = (-4, 1) \)
- \( (x_2, y_2) = (3, 3) \)

Now, substituting the coordinates into the formula:

\[
m = \frac{3 - 1}{3 - (-4)} = \frac{2}{3 + 4} = \frac{2}{7}
\]

Thus, the slope of the line is:

\[
\frac{2}{7}
\]

So the correct answer is:
