How do you determine if a table with an x and a y column is a function or not?
if there is an = sign
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 do you find slope from a table?
Slope is rise over run, so if you have a rise of 2 and a run of 4, then the slope is 0.5. If the table gives rises and runs, then just follow the two until they meet, that should be the slope.
How do you know that a table value is a linear function?
There are several ways to do that. For example, you can actually graph the function. Or, you can check the ratio of the differences between the points. If this ratio (change in y, divided by change in x) is constant, the function is linear.
How can you determine that a set of ordered pairs are a graph table diagram equation a function or mere relation?
In general you cannot. Any set of ordered pairs can be a graph, a table, a diagram or relation. Any set of ordered pairs that is one-to-one or many-to-one can be an equation, function.
What are 3 different methods that can graph a linear equation?
You could put the equation in slope-intercept form or in parent linear function or even make a table of values.
Three methods in graphing linear equation?
table of values,x and y-intercept and slope and y-intercept
What is linear and nonlinear?
A linear or non linear function is a function that either creates a straight line or a crooked line when graphed. These functions are usually represented on a table under the headings x and y.
If given two points from a linear table of values how can you calculate the slope of the equation that was used to generate the table?
Choose two distinct points from the table and designate their coordinates as x1, y1 and x2, y2. The slope of the line then will equal (y2 - y1)/(x2 - x1).

Table to Linear Equation?
You get the linear equation from a table by: Seeing the difference between the y coordinates and that should give you slope. Then find the point where x = 0 and at that point the y coordinate associated with the x is the y intercept and at the point where y = 0 the x coordinate associated is the x intercept. apply the y intercept and slope to the equation y = mx + c with m being the slope and c being the y intercept
What is the slope of the water table called?
Gradient is the steepness of a slope.
How would you find the equation for a linear function when you are given a table of values for the variables?
If the figures in the table are exact and without measurement error then take any two of the points (x1, y1) and (x2, y2) and use these to form the linear relation y - y1 = ((y2 - y1)/(x2 - x1))(x - x1) If, however, you suspect that the values in the table do not exactly follow a linear relationship then use linear regression for which formulae are provided in wikipedia.
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.
What do a Linear Function table look like?
X | Y 1 | m1+b 2 | m2+b 3 | m3+b
How do you find the y intercept of a linear relationship from a table?
When the x-intercept is equal to zero, the value of y is the y-intercept. If you don't have zero on the table, use the formula y=mx+b, where m is the slope, and b is the intercept.
How do you find slope from a table?
Slope is rise over run, so if you have a rise of 2 and a run of 4, then the slope is 0.5. If the table gives rises and runs, then just follow the two until they meet, that should be the slope.
