There is a geometric theorem that says "If two lines in a plane are

Answer 1

Answer:

Step-by-step explanation:

For a line to be perpendicular to another line, its slope must be the negative inverse of the original line’s.

For example, the negative inverse of 3x is -1/3 x.

The line y = 3x is perpendicular to y = -1/3 x. Any line with a slope of 3x is perpendicular regardless of its y-intercept.

Plotted on the graph are the equations:

Y = 3x

Y = 3x + 3

Y = - 1/3 x

As you can see, the lines with the slope of 3x are perpendicular to the third line regardless of their y-intercepts. Only slope matters in regards to parallel and perpendicular lines.
