Write the equation of the line which passes through $(1, –2)$ and is perpendicular to the line with equation $5y – x = 1$.
I know that I need to put the equation into slope-intercept form but what is the step that I take after this.
$$y = \frac 1 5 x + \frac 1 5$$
I read something about the negative reciprocal but that isn't working for me.
Also, here are the possible answers:
a. $5x + y = 3$ ANSWER
b. $5x – y = 1$
c. $x + 5y = –2$
d. $x – 5y = 3$
