Question

Create equations of two lines that are parallel to y=1/2x+5

Answer 1

The lines must have the SAME slope.
Y=1/2x +3

Y= 1/2 x -4. Or may others

Answer 2

Y = 1/2 + 5 , the slope of this equation is 1/2

The equations of the parallel lines must also have a slope of 1/2.

This is because parallel lines have the same value of slope.
