find the slope of the mine contanining (3,9 and (5,-3)

Answer 1

To find the slope of the line passing through two points, you can use the following formula:

slope (m) = (change in y) / (change in x) = (y2 - y1) / (x2 - x1)

Let's call (3, 9) as point 1 with coordinates (x1, y1) and (5, -3) as point 2 with coordinates (x2, y2). Plugging these values into the formula, we get:

m = (-3 - 9) / (5 - 3) = (-12) / (2) = -6

So, the slope of the line containing the points (3, 9) and (5, -3) is -6.
