Find the coordinates of the midpoint for the line with endpoints; A(-1, 5) and B(2, -3). Use the midpoint formula.
pashok25 [27]

Answer:

(0.5, 1)

Step-by-step explanation:

The midpoint formula says that the midpoint between two points (a, b) and (c, d) is:

(\frac{a+c}{2},\frac{b+d}{2})

Here, a = -1, b = 5, c = 2, and d = -3, so the midpoint is:

(\frac{a+c}{2},\frac{b+d}{2})

(\frac{-1+2}{2},\frac{5-3}{2})=(\frac{1}{2} ,\frac{2}{2} )=(0.5,1)

The answer is thus (0.5, 1).
