Write the equation of the line shown in point-slope form. (2,1) (3,8)
Ulleksa [173]

<u>Answer:</u>

The line equation that passes through the given points is 7x – y = 13

<u>Explanation:</u>

Given:

Two points are A(2, 1) and B(3, 8).

To find:

The line equation that passes through the given two points.

Solution:

We know that, general equation of a line passing through two points (x1, y1), (x2, y2) in point slope form is given by

\frac{(y- y1)}{(x-x_1)}= \frac{((y_2- y_1)}{(x_2- x_1 )}

{(y- y1)= \frac{((y_2- y_1)}{(x_2- x_1 )}\times(x-x_1)..........(1)

here, in our problem x1 = 3, y1 = 8, x2 = 2 and y2 = 1.

Now substitute the values in (1)

(y-8) = \frac{(1 - 8)}{(2 - 3)}\times(x- 3)

(y -8) = \frac{(- 7)}{(-1)}(x-3)

y – 8 = 7(x – 3)

y – 8 = 7x – 21  

7x – y = 21 – 8  

7x – y = 13  

Hence, the line equation that passes through the given points is 7x – y = 13

What single transformation was applied to triangle A to get triangle B? Links will be reported​
Alina [70]

Answer:

Rotation:

Step-by-step explanation:

Translation is usually movements like up, down, left, right.

Dilation is when one shape is bigger/smaller than the other, but still congruent.

Reflections are usually done over an axis (x or y), and don't change the degree at which a shape is turned. From looking at the triangles, you can see that one triangle was turned clockwise.

2x+6=3x+4 Write a real-world problem that can be represented by the given equation. Explain what your variable represents.
Slav-nsk [51]

Here, we are required to write a real-world problem that can be represented by the given equation

On the left hand side of the equation, we can say that :

The addition of 6 to twice my cousin's age which gives 2x+6.

On the right hand side, we can say the addition of 4 to thrice my cousin's age which also gives:

3x +4

Ultimately, the real-world problem may be in the form :

Six added to Twice my cousin's age is equal to 4 added to thrice his age.

Also, my variable, x represents my cousin's age.
