Point A is located at (3, 6) and point B is located at (10,−2) .

siniylev [52]

Answer:

(4.75, 4)

Step-by-step explanation:

We are to find the coordinates of the point that partitions the directed line segment AB in 1:3 ration.

For this, we will use the following formula:

$x = x_1 + k(x_2 - x_1)$ , $y = y_1 + k(y_2-y_1)$

where $k$ is the ratio of the first segment to the whole line segment so in this case, it will $\frac{1}{4}$ .

So substituting the given values in the above formula to find the coordinates:

$x = 3 + \frac {1}{4} (10-3) = 4.75$

$y = 6 + \frac{1}{4} (-2-6) = 4$

Therefore, the coordinates of the point that partitions the directed line segment AB in a 1:3 ratio are (4.75, 4).

a line passes through the point (-3,-5) and has a slope of 5 write an equation in point slope form for this line

Tanzania [10]

Answer:

$y=5x+10$

Step-by-step explanation:

1) Plug numbers into slope formula to find $b$ .

$y=mx+b$

$-5=5(-3)+b$

2) Simplify to find $b$ .

$-5=-15+b$

$10=b$

3) Check work.

$-5=-15+10$

This statement is true.

4) Write equation.

$y=5x+10$
