Find the slope of the line that contains the points named.
x(2, -1), y(0,4)

-5/2.

Step-by-step explanation:

The slope = (y2 - y1) / (x2 - x1)  where the 2 points are (x1, y1) and (x2, y2).

Here it is (4 - (-1)) / (0 - 2)

= 5 / -2

= -5/2.

is only a line? i think so

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
