Question 860876
I'm sorry, this question is unclear. Is it {{{y=(-3/7)x+5}}} and {{{y=(-3/7)x-5}}} or something else? Anyway, I just did what I just wrote, and, if I got your question right:
{{{graph( 700, 700, -15, 15, -15, 15, (-3/7)x+5, (-3/7)x-5)}}}
Because these lines are parallel, as they have the same slope, but not the same line, they will never intersect. As they never intersect, there is no 'point' where they will intersect. There are <b>No Solutions</b>
