Mis the midpoint of ab¯¯¯¯¯. m has coordinates (-3, -8) and b has coordinates (-1, 6). what are the coordinates of point a? a. (-5, -22) b. (-4, -1) c. (1, 20) d. (5, 22)

the equation to solve this type of question is :

( x1 + x2 ) divided by two = x value of coordinate

( y1 + y2 ) divided by 2 = y value of coordinate

together these equation will give you an answer for ( x , y )

in this case we would set it up like this :

x1 + x2 divided by two would look like this :

(x + -1) / 2 = -3

(x+ -1) = -6

x = -5

now solve for y

y1 + y2 divided by two :

(x+6) / 2 = -8

(x+6) = -16

x = -22

so the answer would be ( -5, -22 ) which is answer A  

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
