You must find the slope, if it is positive, then the line is always increasing.
If it is negative, then the line is always decreasing.

What is the difference between a linear function and a quadratic equation?
A linear equation describes a line like 2x+1=y. If you were to graph that equation, then it would give you a line. A quadratic equation is like x^2+2x+1=y. Graphing this equation would give you a U shaped graph called a parabola.
How do you find the equation that matches a scattered plot?
use a graphing calculator. chances are, it's not linear; it's probably got some high-degree function with non-whole number coefficients. i think you can download a free graphing calculator online.
How do you find a linear function?
By finding something who's behavior is represented by a linear function and graphing it.
What is the disadvantage of using the substitution method in solving linear equations rather than the graph method?
There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.
Is a linear equation the same as a function?
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
How is graphing a linear equality different from graphing linear equation?
They are the same.
What are the steps to graphing a linear equation?
rise over run.
What are advantages to using the table method when graphing a linear equation?
For a linear I can see no advantage in the table method.
How is graphing a linear inequality different than graphing a linear equation?
In an inequality, you have to shade a side of a line to see show if the possible answers are greater than or equal to it
How is graphing a linear inequality the same as graphing a liner equation?
They are alike in that you graph the lines in the same way, but they are different because you have to shade in one side of the line
Three methods in graphing linear equation?
table of values,x and y-intercept and slope and y-intercept
Which direction would the graph of y-x plus 2 plus 3 open?
The question contains an expression, not an equation. An expression does not have a graph. Furthermore, even if it were an equation, its form suggests that it would be a linear equation and a linear equation does not open in any direction.
How do you figure out the equation of a table with a graphic calculator?
It depends on which calculator! If the data is linear, you can estimate the slope of the line and the y-intercept from graphing the data. By graphing the data, you will be able to tell if it forms a straight line or not.
Is the equation 4y2x linear?
Without an equality sign it is not an equation but an expression
What is the difference between a linear function and a quadratic equation?
A linear equation describes a line like 2x+1=y. If you were to graph that equation, then it would give you a line. A quadratic equation is like x^2+2x+1=y. Graphing this equation would give you a U shaped graph called a parabola.
What is the basic equation for graphing linear equations?
y=mx+b m is slope. slope is rise over run b is y-int
How is graphing a linear inequality the same as graphing a linear equality?
Because the question is tautological. You are asking how something is the same as that very samne thing!
