Question

write an equation of a line parallel to y=2x-7
write an equation of a line perpendicular to y=-5x+9

Answer 1

parallel to y=2x-7 is:
y=2x+35

Answer 2

perpendicular is slope flip and opposite sign,this equation slope is : -5
if paralle slope is -5
if perpendicular is 1/5
than equation is perpendicular to : y=-5x+9
is:
\[y=\frac{1}{5}x -\frac{3}{7}\]
