find the slope, if it exists of the line containing the pair of points. (-19.3, 13.4) and (-17.3, 2.1) The slope m= I came up with m= -4 am I close
he slope is just the difference in the ys over the differences in the xs. That is, when you move 1 in the x direction, how far do you move in the y direction.
-4 isn't very far off, but it's not the exact answer:
Your Ys are 13.4 and 2.1
Your Xes are -19.3 and -17.3
(Cereful to keep them in the right order, to avoid reversing a sign!)
So your answer is:
(13.4-2.1) / (-19.3 - (-17.3))
To find the slope (m) of the line passing through the points (-19.3, 13.4) and (-17.3, 2.1), you can use the formula:
m = (y₂ - y₁) / (x₂ - x₁)
Here, (x₁, y₁) = (-19.3, 13.4) and (x₂, y₂) = (-17.3, 2.1). Plugging these values into the formula, we get:
m = (2.1 - 13.4) / (-17.3 - (-19.3))
m = (2.1 - 13.4) / (-17.3 + 19.3)
m = (-11.3) / 2
Therefore, the slope (m) is -11.3/2, which simplifies to -5.65. It seems like you made a small calculation error. The correct slope is -5.65, not -4.
