The equation for line m is y=-2/3x+5. Which equation represents a line perpendicular to line m?
A) y=3/2x+10
B) y=-2/3x+10
C) y=-3/2x+10
D) y=2/3x+10

Respuesta :

The equation of a line perpendicular to the line [tex]m[/tex] is  [tex]y=-\frac{3}{2}x+5[/tex]

Slope of two perpendicular lines

Two perpendicular lines' slopes are negative reciprocals of each other.

For example, if a line is perpendicular to a line that has a slope [tex]m[/tex], then the slope of the line is [tex]-\frac{1}{m}[/tex].

How to find the equation of a line perpendicular to the given line?

The equation for the line  [tex]m[/tex] is [tex]y=-\frac{2}{3}x+5[/tex]

The slope of a line [tex]m[/tex] is [tex]-\frac{2}{3}[/tex]

The slope of a line that is perpendicular to the line m is [tex]-\frac{1}{\frac{2}{3} }[/tex]

That is [tex]-\frac{3}{2}[/tex]

Thus, the equation of a line perpendicular to the given line is  [tex]y=-\frac{3}{2}x+5[/tex]

Hence, option (C) is correct.
