If y = mx + b is the equation of a line perpendicular to the line y = 5x – 2, what is the value of m?

Respuesta :

The value of m is [tex]-\frac{1}{5}[/tex]

Step-by-step explanation:

The relation between the slopes of two perpendicular line is

  • The product of their slopes is -1
  • That means if the slope of one of them is m, then the slope of the other is [tex]-\frac{1}{m}[/tex]
  • To find the slope of a perpendicular line to a given line, reciprocal the slope of the given line and change its sign

∵ The equation of the perpendicular line is y = mx + b

∴ The slope of the perpendicular line is m

∵ The equation of the given line is y = 5x - 2

- The slope of the given line is the coefficient of x

∴ The slope of the given line = 5

- To find the slope of the perpendicular line to the given line

   reciprocal the slope of the given line and change its sign

∵ The reciprocal of 5 is [tex]\frac{1}{5}[/tex]

∴ The slope of the perpendicular line = [tex]-\frac{1}{5}[/tex]

∵ m is the slope of the perpendicular line

∴ m =  [tex]-\frac{1}{5}[/tex]

The value of m is [tex]-\frac{1}{5}[/tex]
