The line keeps the same slope that it had originally, but it slides straight down,
and crosses the y-axis at a lower number. (That number is actually equal to 'b'.)

Third and fourth
A horizontal line crossing the y axis at 3.
Go what equals 5 units to the left
find the constant of variation and the slope of the given line from the graph of y=2.5x
as the y-intercept increases, the graph of the line shifts up. as the y-intercept decreases, the graph of the line shifts down.

Time is on the x axis and distance is on the y axis. There will be a curve starting at zero (presumably) and going upwards towards the right. The slope of the line at any given x value equals the speed at that point in time. Thus the slope will decrease at the same rate that speed decreases.
Line graphs show increases or decreases in something over time.
If x equals a constant number, the graph will be a vertical line. For example, the graph of x = 5 would be a vertical line that goes through the point (5,0). x equals 5 on every point along this lines.
Because the inverse of a function is what happens when you replace x with y and y with x.
y= -5
The graph is a horizontal line at y=3
That line is horizontal on the graph. Its slope is zero.
The diagonal line collapses into a single point on that line.
