Thank you! im sorry.
No problem. I was just working on it when you reposted.
It had been almost two hours, and your posting was working its way down the page to obscurity, so it was understandable.
The nuisances are people who repost every five minutes and expect someone to be monitoring their every keystroke...
To find the slope of a line passing through two points, you can use the formula:
m = (y2 - y1) / (x2 - x1)
Where (x1, y1) and (x2, y2) are the coordinates of the two points.
Let's solve the first question:
The two points given are (3,2) and (1,-4).
Substituting the values into the formula, we get:
m = (-4 - 2) / (1 - 3) = -6 / (-2) = 3.
Therefore, the slope of the line passing through the points (3,2) and (1,-4) is 3.
For the second question:
The two points given are (-2, 4) and (-4, 6).
Substituting the values into the formula, we get:
m = (6 - 4) / (-4 - (-2)) = 2 / (-2) = -1.
Therefore, the slope of the line passing through the points (-2, 4) and (-4, 6) is -1.
Moving on to the third question:
The two points given are (7,4) and (-5,-2).
Substituting the values into the formula, we get:
m = (-2 - 4) / (-5 - 7) = -6 / (-12) = 1/2.
Therefore, the slope of the line passing through the points (7,4) and (-5,-2) is 1/2.
Finally, for the fourth question:
The two points given are (1,4) and (2,-8).
Substituting the values into the formula, we get:
m = (-8 - 4) / (2 - 1) = -12 / 1 = -12.
Therefore, the slope of the line passing through the points (1,4) and (2,-8) is -12.
