guajiro [1.7K]

Taking the change in y over the change in x. Then the correct option is A.

<h3>What is the equation of a line passing through two points?</h3>

Suppose the given points are (x₁, y₁) and (x₂, y₂), then the equation of the straight line joining both two points is given by

\rm (y - y_1) = \left [ \dfrac{y_2 - y_1}{x_2 - x_1} \right ] (x -x_1)

The equation of the line can be determined by the two known points.

Taking the change in y over the change in x.

Then the correct option is A.
