Question 302706
Vertical lines are of the form {{{x=h}}} where 'h' is any number. Because the vertical line must go through (-3,5), this means that {{{h=-3}}} (because the x coordinate is -3). So the vertical line is {{{x=-3}}}


Similarly, horizontal lines are of the form {{{y=k}}} where 'k' is any number. Since the line must go through (-3,5), we are forced to make 'k' equal to 5 (since the y coordinate is 5). So the horizontal line is {{{y=5}}}
