Point [tex]\( E \)[/tex] is located at [tex]\( (2, -3) \)[/tex] and point [tex]\( F \)[/tex] is located at [tex]\( (-2, -1) \)[/tex].

Find the [tex]\( y \)[/tex] value for the point that is [tex]\( \frac{3}{4} \)[/tex] the distance from point [tex]\( E \)[/tex] to point [tex]\( F \)[/tex].

A. [tex]\( -2.5 \)[/tex]
B. [tex]\( -4.5 \)[/tex]
C. [tex]\( -3.5 \)[/tex]
D. [tex]\( -1.5 \)[/tex]



Answer :

To find the [tex]\( y \)[/tex]-coordinate of the point [tex]\( P \)[/tex] that is [tex]\(\frac{3}{4}\)[/tex] the distance from point [tex]\( E \)[/tex] to point [tex]\( F \)[/tex], follow these steps:

1. Identify the coordinates of points [tex]\( E \)[/tex] and [tex]\( F \)[/tex]:
- Point [tex]\( E \)[/tex] has coordinates [tex]\((2, -3)\)[/tex].
- Point [tex]\( F \)[/tex] has coordinates [tex]\((-2, -1)\)[/tex].

2. Set up the formula to find the coordinates of the point [tex]\( P \)[/tex] which is [tex]\(\frac{3}{4}\)[/tex] of the way from [tex]\( E \)[/tex] to [tex]\( F \)[/tex]:
- For the [tex]\( y \)[/tex]-coordinate, we use the formula:
[tex]\[ y_P = y_1 + \frac{3}{4} \times (y_2 - y_1) \][/tex]
where [tex]\((x_1, y_1)\)[/tex] are the coordinates of point [tex]\( E \)[/tex] and [tex]\((x_2, y_2)\)[/tex] are the coordinates of point [tex]\( F \)[/tex].

3. Substitute the given coordinates into the formula:
- [tex]\( y_1 = -3 \)[/tex] (coordinate of [tex]\( E \)[/tex])
- [tex]\( y_2 = -1 \)[/tex] (coordinate of [tex]\( F \)[/tex])

Plug these values into the formula:
[tex]\[ y_P = -3 + \frac{3}{4} \times (-1 - (-3)) \][/tex]

4. Simplify the expression inside the parentheses:
[tex]\[ -1 - (-3) = -1 + 3 = 2 \][/tex]
So, the equation now becomes:
[tex]\[ y_P = -3 + \frac{3}{4} \times 2 \][/tex]

5. Calculate the term involving the fraction:
[tex]\[ \frac{3}{4} \times 2 = \frac{3 \times 2}{4} = \frac{6}{4} = 1.5 \][/tex]

6. Add this result to [tex]\( -3 \)[/tex]:
[tex]\[ y_P = -3 + 1.5 \][/tex]

7. Calculate the final value:
[tex]\[ y_P = -1.5 \][/tex]

Thus, the [tex]\( y \)[/tex]-coordinate of the point [tex]\( P \)[/tex] that is [tex]\(\frac{3}{4}\)[/tex] the distance from point [tex]\( E \)[/tex] to point [tex]\( F \)[/tex] is [tex]\(-1.5\)[/tex].

The correct answer is:
[tex]\[ \boxed{-1.5} \][/tex]
