If the slope remains the same then the new and old lines are parallel. The whole line moves either up or down.
It moves higher or lower on the plane, while remaining parallel to the original.
Nothing HAPPENS! They can intersect in a point or a line.
The angle that the line makes with the axes changes.
The speed changes.
The line rotates anti-clockwise, from a horizontal to a vertical position.
as the y-intercept increases, the graph of the line shifts up. as the y-intercept decreases, the graph of the line shifts down.
If the slope remains the same then the new and old lines are parallel. The whole line moves either up or down.
It moves higher or lower on the plane, while remaining parallel to the original.
The whole line 'shifts up' by two units, and is parallel to the original line (same slope)
It is translated upwards by 8 units.
it changed by... well it changed... It just changed!
If you mean: y = x and y = x+2 then the lines are then parallel to each
Nothing happens.
It depends on the y-intercept of WHAT is changed.
if the input is changed then the output is also changed.
The slope of a line doesn't change if you zoom in or out.
