No. the slope of parallel lines would be equal but not necessarily zero. How many values can m have in " y=mx +b "? where m is the slope of the lines.

All parallel lines have a zero slope.
The lines all have the same slope.
On the standard Cartesian graph, horizontal lines have zero slope. They all have the equation Y = a number
All lines that have the same slope are parallel to each other. To determine which lines are parallel to the give equation, you must first have to determine the slope of the equation. Notice that your equation is written in y = mx + b form, where m represents slope. In this case, m = 2. Any equation with a slope of 2 is parallel to your given line. For examples of lines that would be parallel, the following are all parallel: y = 2x y = 2x + 1 y = 2x + 2 y = 2x + 100
The straight line equation is y = mx + b. If they do not cross and have the same slope they are parallel; if they cross and the slope (m) of one of them is the negative inverse slope of the other (-1/m) they are perpendicular. Otherwise they are neither
