The midpoint of AB is M(-1, –4). If the coordinates of A are (-3, -7), what are
quester [9]

Answer:

<h3>            B(1, -1)</h3>

Step-by-step explanation:

If M(-1, 4) is midpoint of AB then:

x_M-x_A=x_B - x_M\qquad\quad\ \wedge\qquad y_M-y_A=y_B - y_M\\\\ -1-(-3)=x_B-(-1)\qquad\wedge\qquad -4-(-7)=y_B -(-4)\\\\ -1+3=x_B+1\qquad\qquad\wedge\qquad\ \ -4+7=y_B+4 \\\\ {}\qquad x_B=1\qquad\qquad\wedge\qquad\qquad \ y_B=-1

Please help Determine whether y varies directly with x. If so, find the constant of variation k and write the equation.
dsp73
The linear equation:
y = k x + b
We will use first two values and solve the system of equations:
11 = k * 7 + b   / *(-1)
13 = k * 8 + b
 ---------------------
 -11 = - k * 7 - b
  13 =   k * 8 + b
----------------------
   2 = k       
   13 = 16 + b 
    b = 13 - 16 = -3
   y = 2 x - 3 ( y varies directly with x )
