On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, negative 3) and point B is at (negative 4, 9).
zimovet [89]

Answer: (0,1)

Step-by-step explanation:

If (x_1, y_1) and  (x_2, y_2) are two point son a coordinate plane and (x,y) dividing it in a ratio of m: n.

Then , the coordinates of (x,y) is given by :-

x=\dfrac{nx_1+mx_2}{m+n}

y=\dfrac{ny_1+my_2}{m+n}

Given : On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, - 3) and point B is at (- 4, 9).

Then , the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2 :

x=\dfrac{2(2)+1(-4)}{1+2}=0

y=\dfrac{2(-3)+1(9)}{1+2=1}

Hence, the x- and y- coordinates of point E = (0,1)

Help which is the equation of a line that is parallel to the line represented
-Dominant- [34]
It would be answer A because answer A has the same slope as the equation in the question, none of the other answers have the same slope as 7/6. there is -7/6, but all that means is that the equation is negative. we need a positive equation.
