A line contains the points (10,7) and (10,-8). Write the equation of the line
vagabundo [1.1K]

Given two points (x_1, y_1) and (x_2, y_2), the equation of the line passing through them is

\dfrac{x-x_2}{x_1-x_2}=\dfrac{y-y_2}{y_1-y_2}

This formula, however, only works if the points don't share any of the two coordinates. Otherwise, one of the two conditions is true:

x_1=x_2,\quad y_1=y_2

And at least one of the denominators in the formula above will vanish.

So, if two points share the same x coordinate, they lie on the vertical line x=k, where k is the shared x coordinate.

Similarly, if two points share the same y coordinate, they lie on the horizontal line y=k, where k is the shared y coordinate.

In your case, the x coordinate is the same, so the points lie on the vertical line x=10.

Put the following steps for analyzing mathematical models in the correct order, starting with the first step on the top.
morpeh [17]

Answer: The correct order of the options is 4, 3, 2, 1 and 5.

Explanation:

The steps for analyzing mathematical models are,

To analyzing a mathematical model first we have to defined the problem and identify parameters.

The second step is, defined the data needed. it means determine that which type of data is required according to the problem and parameters and neglect the relevant data.

The third step is collect or gather needed data. To solve the defined problem we need the related data.

The fourth step is arrange or analyse the data according to the requirements.

THe fifth step is after analysing the data draw a reasonable conclusion.

Therefore, the correct order of the options is 4, 3, 2, 1 and 5.

A line has a slope of 2. It passes through the points (1, 2) and (3, y) . What is the value of y? y=
malfutka [58]

Answer:

6

Step-by-step explanation:

To solve this , we use the equation of finding a slope wig a line.

m = (y2 - y1)/(x2 - x1)

From the question, we know that:

y2 = y

x2 = 3

y1 = 2

x1 = 1

m = 2

Hence,

2= (y - 2)/(3 - 1)

2 = (y - 2)/2

4 = y - 2

y = 2 + 4 = 6

Find what x is? 5×3&gt;4+8+x a good help for your brain! ​
MaRussiya [10]

Answer:

x = 2.25 or any number greater

Step-by-step explanation:

5x3 > 4 + 8 + x

Make them equal to each other to get x

5x3 = 4 + 8 + x

(5x)(3) = 12 + x

- x - 3   - 3  - x

4x = 9

\frac{4x}{4} = \frac{9}{4}

x = 2.25

Once you get x plug it in to get the truth of the expression
