Normally on the Cartesian plane using as for example the straight line equation y = mx+c whereas m is the gradient or slope and c is the y intercept.

The starting value for the range of values in a given set of calculations. If you plot the graph of y = x^2 between -10 and +10 the stating value is -10 (minus 10).
That is a result of an absolute value equation. So an Absolute Value Graph
No.
Rise represents the change in y-values on a graph, e.g. if the rise is equal to 10, the y-value changes by 10. Run represents the change in x-values on a graph, e.g. if the run is equal to 5, the x-value changes by 5. knowing both the rise and the run is necessary to calculate the gradient, or slope of a graph - this is done by dividing the rise by the run, in this case it would be equal to 10/5 = 2
A zero of a function is a point at which the value of the function is zero. If you graph the function, it is a point at which the graph touches the x-axis.
