Find the slope of the line that passes through each pair of points.
18. (1,2) and (-3,2)
20. (-4,9) and (10,6)
Can you help me find the answers?
Use the slope equation:
slope = (y2-y1)/(x2-x1)
Of course! I can help you find the slopes of the lines passing through each pair of points.
18. To find the slope of the line passing through the points (1,2) and (-3,2), we can use the formula:
slope = (y2 - y1) / (x2 - x1)
Let's plug in the values:
slope = (2 - 2) / (-3 - 1)
= 0 / -4
= 0
Therefore, the slope of the line is 0.
20. To find the slope of the line passing through the points (-4,9) and (10,6), we'll again use the formula:
slope = (y2 - y1) / (x2 - x1)
Let's substitute the values:
slope = (6 - 9) / (10 - (-4))
= (-3) / (10 + 4)
= (-3) / 14
The slope of the line is -3/14.
Of course! To find the slope of a line that passes through two points, you can use the formula:
Slope (m) = (y2 - y1) / (x2 - x1)
Let's calculate the slope for each pair of points:
18. For the points (1,2) and (-3,2),
Using the formula:
Slope (m) = (2 - 2) / (-3 - 1)
= 0 / -4
= 0
Therefore, the slope of the line passing through these two points is 0.
20. For the points (-4,9) and (10,6),
Using the formula:
Slope (m) = (6 - 9) / (10 - (-4))
= -3 / 14
Therefore, the slope of the line passing through these two points is -3/14.
