Y = -Bx/A + C/A, which is essentially in the form of Y = mx + bĪfter putting the values in the above equation, one can make a linear graph using slope intercept form. Let us understand the process when the values for x and y variables are assumed as follows in the sum below: The same can be graphically plotted to show the linear relationship. If the values of m, x and b are given, one can easily get the value of y. While b is the Y-intercept or the point on the graph crossing the y axis with the x coordinate being zero. Here is a quick formula to understand the linear correlation Correlation Correlation is a statistical measure between two variables that is defined as a change in one variable corresponding to a change in the other. Whether graphically or mathematically, y’s value is dependent on x, which gives a straight line on the graph. Equation of Linear Relationship With Graph Because of budget constraints and varying prices, purchasing more of one will require purchasing lesser of the other. Consider the budget as $2,000 and the grocery items are 12 snack brands ($1-$2 per pack), 12 cold drink brands ($2-$4 per bottle), 5 cereal brands ($5-$7 per pack), and 40 personal care brands ($3-$30 per product). read more and items to be stocked are the dependent variable. the end objective) that is measured in mathematical or statistical or financial modeling. Let us take a real-world example of a grocery store, where its budget is the independent variable Independent Variable Independent variable is an object or a time period or a input value, changes to which are used to assess the impact on an output value (i.e. With this method, it is possible to understand how variation between two factors can affect the result and how they relate to one another. In the field of statistics, it is one of the most straightforward concepts to understand.įor a linear relationship, the variables must give a straight line on a graph every time the values of x and y are put together. It best describes the relationship between two variables (independent and dependent) commonly represented by x and y. The correlation of two variables in day-to-day lives can be understood using this concept.The number of variables considered in a linear equation never exceeds two.It is a statistical method to get a straight line or correlated values for two variables through a graph or mathematical formula.A linear relationship is one in which two variables have a direct connection, which means if the value of x is changed, y must also change in the same proportion.
