Suppose you have a sample of n points for two variables: (x1, y1), (x2, y2), ... (xn, yn). Without going into various statistical considerations (which are nonetheless important) you can estimate the slope of the 'best' line that can be used to estimate the values of y from the values of x using for formula given for beta-hat in the wikipedia article for simple linear regression.

Is 2x equals 7 in standard form or slope-intercept form?
Standard. You need a linear equation in two variables for slope-intercept form.
What type of graph is used to compare two specific variables?
line graph
How do you find the constant and slope for direct variation equations?
For a direct variation equation the constant MUST be 0. Then the ratio of a pair of values of the two variables is the slope.
What are the different ways of graphing linear equations in two variables?
slope intercept form, rise over run
What is Y equals x - 4?
This is the equation of a line in which the slope is 1 and the y-intercept is -4.
How does finding slope compare to finding the rate of change between two variables in a linear relationship?
The slope of a line is the same thing as the rate of change between two variables in a linear relationship.
What graph is used to compare two variables?
A line graph is used to compare two specific variables.
When a graph shows two variables are directly proportion the slope will be?
If the two variables are directly proportional, then the slope can be any number,but the y-intercept has to be zero ... the line must go through the origin.
A graph of two simultaneous linear inequalities in two variables that have no intersecting regions must contain two lines with the same slope?
A graph of two simultaneous linear inequalities in two variables that have no intersecting regions must contain two lines with the same slope.
If two variables have a negative linear correlation is the slope of the least squares negative?
Negative
The two axes on a line graph allow the viewer to compare?
two different variables
Is 2x equals 7 in standard form or slope-intercept form?
Standard. You need a linear equation in two variables for slope-intercept form.
What type of graph is used to compare two specific variables?
line graph
How do you find the constant and slope for direct variation equations?
For a direct variation equation the constant MUST be 0. Then the ratio of a pair of values of the two variables is the slope.
What does trend mean you math terms?
A trend is a math term. It is on a line graph. It is a slope between two variables.
What are the different ways of graphing linear equations in two variables?
slope intercept form, rise over run
True or false A graph of two simultaneous linear inequalities in two variables that have no intersecting regions must contain two lines with the same slope?
True
