On a time graph, constant speed is represented by a straight line with a constant slope. The slope of the line indicates the speed of the object – the steeper the slope, the faster the speed, and the shallower the slope, the slower the speed.

Your statement is correct. y=mx+b when m is the slope and b is the y-intercept.
The "steepness" of a line is called the slope. The slope represents the the amount of change in the y-direction of the line per every change in the x-direction. This is represented mathematically by slope = Δy/Δx Δy is also called the "rise" and Δx is also called the "run". The steepness can also be called the gradient, which is represented by an angle. The gradient can be calculated from the slope by using the formula gradient = tan(slope).
