How is the two point formula used to find the equation of a line when 2 points are known?
a.
taking the change in y over the change in x
c.
dividing the first y by the first x
b.
taking the change in x over the change in y
d.
dividing the first x by the first y

Answers

Y=my+b
which is 2=5(3)+b
2=15+b
-13=b
When two points are given.
Using any specific formula or what?
The point-slope form equation is best used to find the equation of a line when you are only given the slope and one point on the line, or two points, in which you can get the slope from.
The first step to finding the equation of a line when 2 points are known
the first step would be to use the slope formula to find the slope of the line
The equation of a line is mx+b
Solutions 

The two-point form of an equation is best used to find the equation of a line when two points are given. 
Point slope give a point on the line and the slope

it is best used when you are given a point on the line and the slope
or
it is also good when you knwo how to find the slope and you are given 2 points

I would go wiith first option that I said

A. Taking the change in y over the change in x.

Step-by-step explanation:

We know that,

The two-point form of a line is given by,

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

For this form, the ordered pair are already given.

So, we have to calculate, \frac{y_2-y_1}{x_2-x_1}.

That is, we need to find,

The ratio of change in y-values and x-values.

Thus, the two-point form is used to find the equation of a line by 'Taking the change in y-values over the change in x'.

Hence, option A is correct.

To find the slope of a line, you would find the change in y over the change in x, where the rise of a slope is defined by the y coordinate and the run of the slope is defined by x.
