The coordinates of point a are 30 units of x and 70 units of y. the coordinates of point b are 28 units of x and 76 units of y.
Leni [432]
The first thing you should know is that the slope of the line that passes through two points, by definition is given by:
 m = (y2-y1) / (x2-x1)
 Substituting the values we have:
 m = (76-70) / (28-30)
 m = -3
 answer:
 the slope of the line between points a and b is
 m = -3

If M=(2,5) is the midpoint of AB, and A=(0,-1), then the coordinates of B are _____.
faust18 [17]

Answer:

The point M(Mx, My) is mid-point of AB with A(Ax, Ay) and B(Bx, By).

=> 2*Mx = Ax + Bx => 2*2 = 0 + Bx => Bx = 4

=> 2*My = Ay + By => 2*(5) = -1 + By => By = 11

=> B(4, 11)

=> Option A is correct

Hope this helps!
