Question

How is the two point formula used to find the equation of a line when 2 points are known?

Answer 1

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.

:)

Answer 2

Answer:

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.
