If you are looking for the angle between a line and another, then it is usually represented by Ө (theta).
If you're looking for the gradient of a line, use m = rise/run or m = y2 - y1 / x2 - x1 , where m is the gradient, (x1,y1) and (x2,y2) are two fixed points on the cartesian plane.

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).
Without an equality sign it is not an equation but when a straight line equation is parallel to another straight line the slope remains the same but the y intercept is different
