The equation of a line is shown below.

y = fraction reading 1 over 5x - 9

What is the equation of a line which is perpendicular to this line and passes through (1, 58)?

y = 5x - 63

y = -5x + 63

y = 9x - 63

y = 9x + 63

Question

The equation of a line is shown below.

y = fraction reading 1 over 5x - 9

What is the equation of a line which is perpendicular to this line and passes through (1, 58)?

 y = 5x - 63

 y = -5x + 63

 y = 9x - 63

 y = 9x + 63

anonymous · Answer

the line
$$y=\frac{1}{5}x-9$$ has slope $\frac{1}{5}$
 a perpendicular line will have slope $-5$

anonymous · Answer

only this line $ y = -5x + 63 $ has slope $-5$ so that is the only possible answer
