Question

Is y= -9/5x + 1/5 perpendicular to y= 5/9x + 2/9

Answer 1

The given lines are perpendicular

Step-by-step explanation:

if Two lines are perpendicular then their slopes are

m$m_{1}=-\frac{1}{m_{2}}$

Where m₁ is slope of first line and m₂ is the slope of second line.

Since the lines are in slope-point form the standard form is:

$y=mx+b$

where m is the slope

The slope of first line y= -9/5x + 1/5 is: m₁ = -9/5

The slope of second line y= 5/9x + 2/9 is: m₂= 5/9

So,  m$m_{1}=-\frac{1}{m_{2}}$ i.e $-\frac{9}{5}=\frac{5}{9}$

So, The given lines are perpendicular
