Find an equation of the line passing through the pair of points (2,3) and (5,9). Write the equation in the form Ax + By = C.
8090 [49]

Answer:

- 2x +  y  = - 1 , so the B is correct.

Step-by-step explanation:

+ Because of "the line passing through the pair of points (2,3) and (5,9)", that means the line has the equation y = ax + b where a = (9-3)/(5-2)= 6/3= 2

+ So the equation is y = 2x + b.

+ Then we replace x= 2 and y= 3 into y = 2x + b for finding  like:

3 = 2*2 + b or 3 = 4 + b, so we find b = 3 - 4 = - 1.

+ The equation of this line is y = 2x - 1 or in the form:

                                  2x - y - 1 = 0 (or -2x + y = -1)

Have a good day!

How do u do percentage​
lbvjy [14]

Answer:

Step-by-step explanation:

Ill try to break this down, simply:

When we talk about percentages we are talking about how much part of something we have and the percent sign is a just a symbol representing that.

Lets say we have 2 out of 10 apples and we need to convert this to a percentage

First think about how many apples we have in total... and that would be 10, and then how many apples we currently have being 2:

So if we put the part that we have over the whole thing we get:

\frac{2}{10}

So now lets turn this into a decimal, when its something over 10 its really easy, all we have to do is move the decimal back one place!

So we have 2 and if we move the decimal back one place we get .2 or 0.2

Now we have our decimal, to convert this into a percentage all we have to do is multiply our decimal by 100

So:

0.2 x 100 = 20%

All you do when you multiply by 100 is move the decimal back over 2 places one place for each zero so:

0.2 --> 2. --> 20.

Which gives us again 20%
