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.
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.
y= -5
Line graphs show increases or decreases in something over time.
Because the inverse of a function is what happens when you replace x with y and y with x.
The graph is a horizontal line at y=3
That line is horizontal on the graph. Its slope is zero.
Third and fourth
The diagonal line collapses into a single point on that line.
A horizontal line crossing the y axis at 3.
