The graph of [ y = 4x + 2 ] is a straight line with a slope of 4.Any line with a slope of 4 is parallel to that one, and any line parallel to that one has a slope of 4.
Minus one half, (-1/2).
That's true at the point (0.5, 0.25) where the slope of the graph is ' 1 ' .
It has no slope and is parallel to the x axis
That line is horizontal on the graph. Its slope is zero.

It has no slope and is parallel to the x axis
x = negative 1 is a vertical straight line parallel to the y axis at x = -1 ; its slope is infinite

The slope or gradient is the same and would run parallel but the intercept on the y axis would be at -1
The graph of [ x = 1 ] is a straight vertical line, parallel to the y-axis and one unit to the right of it. According to all the normal processes of naming the slope of a line on a graph, you would say that the slope of this line is "infinity", but the official way to say it is that the slope is "undefined".
The slope is 4
That line is horizontal on the graph. Its slope is zero.
