Andy is wrong.
3/5 = 12/20
1/4 = 5/20
Add them up
12/20 + 5/20 = 17/20
17/20 is not equal to 4/9

1/4 = 5/20
12/20 + 5/20 = 17/20

EH = 9

FH = 7

EG = 6

EF = EH - FH

Point c partitions line segment AB in the ratio 1:3. What is the y-coordinate of c.
Veseljchak [2.6K]

The y-coordinate of c is -4 if the Point c partitions line segment AB in the ratio of 1:3.

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

We have two points:

A(-4, -7), and B(12, 5)

Let's assume A(x1, y1)  and B(x2, y2)

The ratio is 1:3 = m:n

Let's assume the y-coordinate is a

From the section formula:

\rm a = \dfrac{my_2+ny_1}{m+n}

\rm a = \dfrac{1\times5+3\times(-7)}{1+3}

a = -4

Thus, the y-coordinate of c is -4 if the Point c partitions line segment AB in the ratio of 1:3.
