Why use slopes?
The slope of a graph provides general information about a graph. It tells you how much the y value of the graph increases (or decreases, if the slope is negative) for a given increase in x value. if you look at the general equation of a graph y = a x + b the value "a" represents the slope and the "b" value represents the value of y when x = 0. When the graph is not a straight line, the discussion gets more complicated, however the slope still describes changes in the value of the graph (you have to use calculus for this situation.)
What can you say about the graph of Ax plus By equals C if B is equal to zero?
If B=0, then the graph does not depend on the value of y. This is a vertical line at x = C/A
What is the graph of a linear equation?
[ y = mx + b ] is.m = the slope of the graphed lineb = the 'y' value where the graphed line crosses the y-axis.
How do you find range in a graph?
Take the largest value in the graph and subtract the smallest value from it.

The graph at the right shows a function, f, graphed on the domain 0 less equal x less equal 8. The section from A to B is a straight segment. The section from B to C is represented by y = (x - 5)². graph split Find the slope of the segment from A to B. Find the x-coordinate of the relative minimum value of the graph from B to C. Find the value of f (3) + f (4) + f (6) + f (7).
