## Which is the best definition of a velocity graph?

1. Velocity ( s-t) Graphs Distance-time graph of an object travelling at constant speed. This general graph represents the motion of a body travelling at constant velocity. The graph is linear (that is, a straight line). Recall that linear equations have the general form y = mx (where m is a constant and x is a variable).

### What is the slope of a linear graph called?

The graph is linear (that is, a straight line). Recall that linear equations have the general form y = mx (where m is a constant and x is a variable). The number m is called the slope of the line (the vertical rise over the horizontal run). In the above graph, we have the function: Velocity is constant and time is a variable.

#### How to plot the planar curve X and Y?

ezplot (x,y) plots the parametrically defined planar curve x = x(t) and y = y(t) over the default range 0 <= t <= 2π or over a subinterval of this range. ezplot (x,y,[tmin,tmax]) plots x = x(t) and y = y(t) over the specified range tmin <= t <= tmax.

When does the plotting range apply to both variables?

For a univariate expression or function, the plotting range applies to that variable. For an equation or function of two variables, the plotting range applies to both variables. In this case, the range is the same for the abscissa and the ordinate.

How to plot a function using ggplot equivalent of curve?

## How is a line graph different from a scatter plot?

Line graphs are like scatter plots in that they record individual data values as marks on the graph. The difference is that a line is created connecting each data point together. In this way, the local change from point to point can be seen.

### When to use a curved line in a graph?

When a curved line is used, it is typically expressed as either a second order (cubic) or third order (quadratic) curve. Higher order curves may follow the actual data points more closely, but rarely provide a better mathematical description of the relationship.
