19. Elein and Naya wanted to meet between their houses at midpoint (4,1). If Elien's house is at point
A. (7,-1.5)
(10,-4).
B. (-2,6)
Find the coordinates of Naya's house.
C. (0,0)

Step-by-step explanation:

Given

Required

Determine the coordinates of Naya's

Midpoint is calculated as:

In this case:

So, we have:

Multiply through by 2

By comparison:

So:

So, the coordinate is:

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
