Answer:

The equation of line with given points is  y - 4 = 3 ( x + 2 ) .

Step-by-step explanation:

Given as :

The points of line are ( 1 , 13 )   and    ( - 2 , 4 )

The point slope intercept equation of line is

y - y_1 = m ( x -  x_1 )

Where m is the slope of line

So , Slope , m = \frac{y_2 - y_1}{x_2 - x_1}

Or, m =  \frac{4 - 13}{ - 2 - 1}

Or, m =  \frac{ - 9}{ - 3}

∴    m = 3

Now The equation of line is

y - y_1 = m ( x -  x_1 )

Or. y - 13 = 3 ( x -  1 )

Or, y - 13 = 3 x - 3

Or, y = 3 x - 3 + 13

∴   y = 3 x + 10

I.e y - 4 = 3 x + 6

Or, y - 4 = 3 ( x + 2 )

Hence The equation of line with given points is  y - 4 = 3 ( x + 2 ) . Answer

Pls, can someone answer this, Explain, using words and numbers, how to subtract 7x - ( 6x + 13). Remember to include the solutio
Hitman42 [59]
So first you distribute the negative to the 6x and 13 which will flip the sign of both of them to -6x and -13 so take away the parentheses and the equation is now 7x-6x-13. You combine the x’s and you get 1x-13 or x-13

Answer:

Option C is the correct choice that is y

Step-by-step explanation:

As this is a multiple choice question we will reduce the options and work on it with the given points (0,-2),(-2,-3)

Note:We know that \leq ,\geq where there is = sign associated with it have a straight line graph there is no breaking in the line.

And when there is simply we have a dashed line when we plot it on a graph.

So option B and D are discarded.

Now one-by one we will put the values (x,y)\ (-2,3) to know which equation it satisfies.

If we put y=3 then x=-2.

So working with option A.

y

Plugging the values.

3

And we know that x must be equal to -2 so this is not the right answer.

We are left with only one choice that is C .

So option C is the correct option of the above inequality.
