What is the slope of a line that is perpendicular to the line y=-3x
exis [7]

slope of a line that is perpendicular to the line y=-3x is 1/3

What is slope of line?

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively. where "m" represents a line's slope. So, the slope of a line is tanθ.

y=-3x

tanθ=slope = y/x= -3

Slope(M) of this equation is -3

Let the slope of its perpendicular line is m

As we know that the product of the slopes of perpendicular lines is -1

so,

M*m =-1

-3 * m= -1

m=1/3
