The answer is 5 3/4.............
Answer:
y-coordinate = 0
Step-by-step explanation:
Consider the below diagram attached with this question.
Section formula:
If a point divides a line segment in m:n whose end points are
and
, then the coordinates of that point are

From the below graph it is clear that the coordinates of end points are J(1,-10) and K(7,2). A point divides the line JK is 5:1.
Using section formula, the coordinates of that point are




Therefore, the y-coordinate of the point that divides the directed line segment from J to k into a ratio of 5:1 is 0.
The area of the figure above is 53
Y = 3000x + 28000
y = 2800x + 30000
3000x + 28000 = 2800x + 30000
200x = 2000
x = 10
