Question

For question 4 I know it has the answer already but I just need the steps by step for it its the midpoint formula. If you know can you help me out

Answer 1

M = ((-4+5)/2, (-1+3)/2) = (1/2, 2/2) = (1/2, 1)

Explanation:

The midpoint (M) of segment AB is ...

M = (A +B)/2

That is, for coordinates A = (ax, ay) and B = (bx, by), the midpoint is ...

M = ((ax, ay) +(bx, by))/2

M = ((ax+bx)/2, (ay+by)/2) . . . . midpoint formula

__

For A(-4, -1) and B(5, 3), M will be ...

M = ((-4+5)/2, (-1+3)/2) = (1/2, 2/2)

M = (1/2, 1) . . . . as you know
