#x=7#

Explanation:

To convert from #color(blue)"polar to rectangular form"#

#color(orange)"Reminder " color(red)(|bar(ul(color(white)(a/a)color(black)(x=rcostheta , y=rsintheta)color(white)(a/a)|)))#

also #color(red)(|bar(ul(color(white)(a/a)color(black)(sectheta=1/(costheta))color(white)(a/a)|)))#

#rArrr=7sectheta=7/(costheta)#

#rArrrcostheta=7rArrx=7#

which is a vertical line, parallel to the y-axis.
