perpendicular y=-2/5 ,(-2,1)

perpendicular

y = - \frac{2}{5}, (- 2, 1)

x = - 2

Solution steps

Find the line

y = mx + b

perpendicular to

y = - \frac{2}{5}

that passes through

(- 2, 1)

Find the slope of

y = - \frac{2}{5} : m = 0

Compute the slope of the perpendicular line:

m_{p} = \infty

Find the line with slope m=

\infty

and passing through

(- 2, 1) : x = - 2

x = - 2
