Question 1158548
The parallel line has the same slope as 4/5 x-7. So the line is in the form {{{y=(4/5)x+b}}}. Plugging in  -20 for x and 7 for y, we get {{{7=(4/5)*-20+b}}}. {{{7=-16+b}}}. {{{b=7+16=23}}}. So the equation is {{{y=(4/5)x+23}}}. <br/> {{{graph(500,500,-20,20,-20,20,y=(4/5)x-7,y=(4/5)x+23)}}}.
