Answer:
B(1, 0)
Step-by-step explanation:
A(5, -4) ⇒ [tex]x_A=5,\quad y_A = -4[/tex]
M(3,-2) ⇒ [tex]x_M=3,\quad y_M=-2[/tex]
Point M(3, -2) being the midpoint of AB means that [tex]x_M-x_A=x_B-x_M[/tex]
[tex]3-5=x_B-3\\\\-2=x_B-3\\\\x_B=1[/tex]
and [tex]y_M-y_A=y_B-y_M[/tex]
[tex]-2-(-4)=y_B-(-2)\\\\-2+4=y_B+2\\\\y_B=0[/tex]
