The formula 'y=mx+b' describes a straight line, where 'm' is the slope, and 'b' is the y-intercept.
Any two lines with the same slope will be parallel to each other, so any line whose 'y=mx+b' formula has the same 'm' value and a different 'b' value will satisfy the requirements of your questions.
So, for instance:
y = 10x + 1 and y = 10x + 2 are the formulas for two parallel lines with a slope of 10.
To get coordinates on these lines, just plug in values for 'x' and solve for 'y'. For instance:
(0,1), (1,11), and (2,21) are on the line 'y = 10x + 1', and
(0,2), (1,12), and (2,22) are on the line 'y = 10x + 2'.
