Acceleration The slope of the line of a speed-versus-time graph will give you acceleration.
In the equation of a straight line (when the equation is written as  y = mx + b ), the slope is the number  m  that is multiplied on the x, and  b  is the y-intercept, where the line crosses the y-axis.n this lesson, we are going to look at the real world meanings that slope and y-intercept can have. We have seen that the slope of a line measures how much the value of y changes for every so much that the value of x changes. For instance, in the line y = (3/5)x 2, the slope is m = 3/5.
