if the slope is 2x + 5 then on the y axis put a point at (0,5). then you count up 2 and right 1 and your next point should be (1, 7) then count up 2 and over 1 and your next point should be (2,9). Now you do the same for the other part of the graph. At (0,5) count down 2 and left 1 and your next point should be (-1, 3) and then count down 2 and left 1 and the next point should be (-2,1)

Lines with no slope are horizontal lines or flat lines
Lines that have the same slope are said to be parallel lines.
The slope between two parallel lines is identical. This is because parallel lines have the same slope and will never intersect. The slope of a line is a measure of its steepness, and when two lines are parallel, they will have the same steepness, resulting in the same slope. Therefore, the slope between two parallel lines will always be equal.
Horizontal lines always have a slope of zero. (i.e completely flat, level surfaces have a slope of zero). However a line does not have to have a slope of zero in order to be a line.
No, lines have the same slope if and only if they are parallel to each other.
