How do you determine if the graph of a quadratic function has a min or max from its equation?
If x2 is negative it will have a maximum value If x2 is positive it will have a minimum value
When does the equation yax describes the graph of a lines if the value of a is a negative what is the line?
When the equation (y = ax) describes the graph of a line and (a) is negative, the line has a negative slope. This means that as the value of (x) increases, the value of (y) decreases, resulting in a downward slant from left to right. The line will intersect the origin (0,0) and will extend infinitely in both directions.
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 relationship does a linear graph shows?
A linear graph shows a linear equation in which the value of one variable depends on the value of the other variable.
How do you find the magnitude of the y-intercept?
-- In the equation of the graph, set x=0. -- Solve the equation for 'y'. -- The value you get for 'y' when x=0 is the y-intercept.
The equation y equals ax describes the graph of a line If the value of a is positive the line?
goes through the origin, up and to the right

Does The equation y ax describes the graph of a line If the value of a is negative the line?
y=ax is a line that goes through the origin. If a is negative the left side is up. If it is zero it is level. If it is positive the right side is up.
What do you call a V-shape on a graph?
That is a result of an absolute value equation. So an Absolute Value Graph

What is the corner point of the graph of an absolute value equation called?
vertex
The value 11.7 represents the of the graph of the following linear regression equation?
slope
How can you find coordinates on a line graph?
Select any value for one of the variables in the graph and solve the equation to get the other variable.
What is the corner point of a graph of an absolute value equation?
It is sometimes the point where the value inside the absolute function is zero.
What equation has a steeper line?
For a positive number, as the slope(y=mx+b where m is the slope) gets greater in value, the line gets steeper when plotted on a graph. For a negative number, as the slope(y=mx+b where m is the slope) gets greater in value, the line gets less steep when plotted on a graph.
