Can you please explain how you got the slope for these I really don't understand Sams I think it is with the 2/11/22 and 2/4/8 thank you
To find the slope of a line, you need two points on that line. In this case, the given points are (2,11) and (22,8) for Sam's question.
The slope (m) can be calculated using the formula:
m = (y₂ - y₁) / (x₂ - x₁)
Using the coordinates, we can substitute the values into the formula:
m = (8 - 11) / (22 - 2)
= -3 / 20
Therefore, the slope of this line is -3/20.
If you have any follow-up questions, please, let me know.
To find the slope between two points, you can use the formula:
slope = (change in y-coordinates) / (change in x-coordinates)
Let's apply this formula to the points (2, 11) and (2, 4) to find the slope.
Step 1: Identify the given points.
Point 1: (2, 11)
Point 2: (2, 4)
Step 2: Determine the change in y-coordinates.
The change in y-coordinates is calculated by subtracting the y-coordinate of the first point from the y-coordinate of the second point.
11 - 4 = 7
Step 3: Determine the change in x-coordinates.
The change in x-coordinates is calculated by subtracting the x-coordinate of the first point from the x-coordinate of the second point.
2 - 2 = 0
Step 4: Calculate the slope.
Using the formula: slope = (change in y-coordinates) / (change in x-coordinates)
slope = 7 / 0
Note: Division by 0 is not possible, and therefore, the slope is undefined for these points. The reason for this is that the two points have the same x-coordinate (2), resulting in no change in the x-coordinate. Thus, the line between the two points is vertical, and the slope of a vertical line is undefined.
In summary, for the points (2, 11) and (2, 4), the slope is undefined.
