Yuliya22 [10]3 years ago
7 0

Answer:

D. y - y_0 = m(x - x_0).

Step-by-step explanation:

The equation of a line can be written in the point-slope form if we know the the coordinates of a point the line passes through which is (x_0, y_0). And if we also know the slope = m of the line.

Therefore, the point-slope equation is given as:

y - y_0 = m(x - x_0)

A system is:
1.25 x + 2.25 y = 16
x + y = 8
---------------------------
y = 8 - x
1.25 x + 2.25 * ( 8 - x ) = 16
1.25 x + 18 - 2.25 x = 16
- x = 16 - 18
- x = - 2
x = 2
y = 8 - 2
y = 6

Given three collinear points A,B,C with B between A and C, four different rays can be named using points AB, BA, BC, CB. How man
Dmitry [639]

Answer:

Given n collinear points, 2(n -1) or 2n - 2 rays can be named

Step-by-step explanation:

When we talk of collinear points, we mean points that lie on the same straight line.

For 3 collinear points we can have 4 rays

For 4 collinear points, let’s say ABCD

A B C D

The rays are AB BA BC CB CD and DC making a total of 6

For 5 collinear points,

A B C D E

The rays are;

AB BA BC CB CD DC DE ED which makes a total of 8

For 6 collinear points, we have;

A B C D E F

The rays are;

AB BA BC CB CD DC DE ED FE EF which makes a total of 10

So what pattern do we notice?

3 points 4 rays

4 points 6 rays

5 points 8 rays

6 points 10 rays

7 points 12 rays

So using the pattern

n rays = 2n - 2 rays or simply 2(n - 1) rays
