7. Find the slope of the line given its graph

Without a specific graph or equation given, it is not possible to determine the slope of the line.

To find the slope of a line given its graph, you need to take two points on the line and calculate the difference in the y-coordinates divided by the difference in the x-coordinates.

From the given graph, we can see that there are two points on the line: (-10, a) and (1, 9).

Next, we can calculate the difference in the y-coordinates: 9 - a.

And the difference in the x-coordinates: 1 - (-10) = 11.

Finally, we divide the difference in the y-coordinates by the difference in the x-coordinates to find the slope:
slope = (9 - a) / 11.

Therefore, the slope of the line is (9 - a) / 11.

To find the slope of a line given its graph, you need to choose two points on the line. Let's choose the points (-10, -1/9) and (a, 1), where a is an unknown value.

The slope (m) is defined as the change in y-coordinates divided by the change in x-coordinates between the two points.

Using the coordinates (-10, -1/9) and (a, 1), the change in y-coordinates is given by:
1 - (-1/9) = 1 + 1/9 = 10/9.

The change in x-coordinates is given by:
a - (-10) = a + 10.

Therefore, the slope (m) is:
m = (change in y-coordinates)/(change in x-coordinates) = (10/9)/(a + 10) = 10/(9(a + 10)).

So, the slope of the line is 10/(9(a + 10)).
