What are the coordinates of the point on the directed line segment from (–9, -7) to
pentagon [3]

Answer:

Step-by-step explanation:

Saving the long, drawn out derivation of the formulas to find the x and y coordinates of the directed point, suffice it to say that it is:

x coordinate: \frac{bx_1+ax_2}{a+b} and

y coordinate: \frac{by_1+ay_2}{a+b}

where x1, x2, y1, and y2 are the coordinates from the given points and a and b are the numbers in the ratio, namely a = 3 and b = 4. Filling in accordingly:

the x coordinate of the directed point is

\frac{4(-9)+3(-2)}{7} which simplifies down to -6, and

the y coordinate of the directed point is

\frac{4(-7)+3(7)}{7} which simplifies down to -1.

The coordinate of the point is (-6, -1). Write that down so you don't forget it.
