A line passes through the points (4,-1) and (2,3. what is the slope of this line?
A. -1/2
B. -2
C. 1/2
d. 2
Let me help.. give me a sec

I think the correct answer is 2
the formula is slope=(y^2-y^1)/(x^2-x^1)

I don't believe +2 is right.
You should do (y2-y1)/(x2-x1) and see if you obtain 2.
To find the slope of a line passing through two points, you can use the formula for slope, which is (y2 - y1) / (x2 - x1).
Given the points (4, -1) and (2, 3), let's assign x1 = 4, y1 = -1, x2 = 2, and y2 = 3.
Substituting these values into the slope formula, we get:
(y2 - y1) / (x2 - x1) = (3 - (-1)) / (2 - 4) = (3 + 1) / (-2) = 4 / (-2) = -2.
Therefore, the slope of the line passing through the points (4, -1) and (2, 3) is -2.
So, the correct answer is option B. -2.
