The midpoint of AB is M(5, -5). If the coordinates of A are (3, -6), what are the coordinates of B?

(7,-4)

Step-by-step explanation:

let b be x2,y2

then apply mid point formula

x=(x1+x2)/2

y=(y1+y2)/2

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
