-- Call the number 'N'.

-- The sum of the number and six is (N + 6).

-- Twenty added to it is    20 + (N + 6)

-- That whole thing is twenty-seven           

                                              <u>20 + (N + 6) = 27</u>

Subtract  20  from each side:          (N + 6) = 7

Subtract  6  from each side:            <em>  N      =  1

</em>
==================================

Check:<em>  </em>

Put your solution into the statement and see if the statement is true.

     "Twenty added to the sum of (1 and six) is twenty-seven."<em>

</em>
That's true.            <em>yay !</em><em>

A line passes through the points (2,4) and (5,6) .
Alenkinab [10]

Answer:

Option B and D are correct.

Step-by-step explanation:

Given: A line passes through the points (2,4) and (5,6).

* Case 1:

If a line passes through the points (2, 4) and (5, 6)

Point slope intercept form:

for any two points (x_1,y_1) and (x_2, y_2)

then the general form y -y_1=m(x-x_1) for linear equations where m is the slope given by:

m =\frac{y_2-y_1}{x_2-x_1}

First calculate slope for the points (2, 4) and (5, 6);

m = \frac{y_2-y_1}{x_2-x_1} =\frac{6-4}{5-2} = \frac{2}{3}

then, by point slope intercept form;

y-4=\frac{2}{3}(x-2)

* Case 2:

If a line passes through the points (5, 6) and (2, 4)

First calculate slope for the points (5, 6) and (2, 4);

m = \frac{y_2-y_1}{x_2-x_1} =\frac{4-6}{2-5} = \frac{-2}{-3}= \frac{2}{3}

then, by point slope intercept form;

y-6=\frac{2}{3}(x-5)

Yes, the only equation of line from the given options  which describes the given line are;

y-4=\frac{2}{3}(x-2)  and y-6=\frac{2}{3}(x-5)
