What is the slope of the line containing the points (-9,2) and (3,14)?
slope=changeinY/changeinX=(2-14)/(-9-3)=-12/(-12)=1
To find the slope of a line containing two points, you can use the formula:
slope = (y2 - y1) / (x2 - x1)
In this case, the coordinates of the two points are (-9, 2) and (3, 14).
Using the formula:
slope = (14 - 2) / (3 - (-9))
= 12 / 12
= 1
Therefore, the slope of the line containing the points (-9,2) and (3,14) is 1.
To find the slope of the line containing the points (-9,2) and (3,14), you can use the formula for slope:
slope = (change in y-coordinates) / (change in x-coordinates)
Step 1: Determine the change in y-coordinates.
The y-coordinate of the first point is 2, and the y-coordinate of the second point is 14. So the change in y-coordinates is 14 - 2 = 12.
Step 2: Determine the change in x-coordinates.
The x-coordinate of the first point is -9, and the x-coordinate of the second point is 3. So the change in x-coordinates is 3 - (-9) = 12.
Step 3: Calculate the slope.
Now we can use the formula for slope:
slope = (change in y-coordinates) / (change in x-coordinates)
slope = 12 / 12 = 1
Therefore, the slope of the line containing the points (-9,2) and (3,14) is 1.
