Answer :

The most appropriate choice for slope of a line will be given by-

Two lines are perpendicular to one another when the product of their slopes is equal to -1

What is slope of a line?

Slope of a line is the tangent of the angle which the line makes with the positive direction of x axis

If [tex]\theta[/tex] is the angle which the line makes with the positive direction of x axis, then slope of the line is given by

[tex]m = tan\theta[/tex]

If the line passes through [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex]

slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Here,
