The rate of readjust is a ratio that to compare the readjust in values of the y variables to the adjust in worths of the x variables. If the rate of readjust is continuous and linear, the rate of adjust is the slope of the line. The slope of a line may be positive, negative, zero, or undefined.

### Dependent and also Independent Variables

Another way to look in ~ the rate of change is come look in ~ the meanings of the variables themselves. The y variables are the dependent variables and the x variables are the live independence variables. Expect that a worker is payment $10.00 every hour. The quantity of the paycheck depends on the number of hours worked, so the worker is paid $160.00 because that 16 hrs one week, and $180.00 because that 18 hrs the following week. The readjust in the dependent change is 180-160 or 20 and also the adjust in the independent change is 18-16, or 2, so the price of adjust is 20/2, or 10/1.

### Linear price of Change

If the relationship between the dependent and independent variables is linear, the rate of change is the exact same between any type of two sets of variables follow me the line. Expect that the worker in the above example is paid $50.00 for 5 hours one week and also $80.00 because that 8 hrs the following week. The change in the dependent change is 80-50, or 30, and also the change in the independent change is 8-5, or 3. The rate of adjust is 30/3, or 10/1, the same rate of readjust as in the very first example. In a linear relationship, the rate of readjust is constant.

### Type that Slope

The slope of a heat can also be described by that direction. In the relationship of the paycheck and variety of hours worked, the heat rises indigenous left come right. The more hours worked, the greater the paycheck, v a optimistic slope. Intend a plane is landing. The relationship between its elevation and also the time from its highest altitude is a falling line from left come right, a an unfavorable slope. If the relationship is a horizontal line, so the no adjust occurs, the slope is zero. However, if the partnership is a vertical line, the slope is undefined. The is additionally not a function, together there space multiple values of y because that one value of x.

### Slope Formula

The slope of a line is usually represented by the change m. It is expressed by the proportion of the distinction in worth of y variables come the difference in value of x variables. In algebraic terms, if (x1, y1) (x2, y2) are the coordinates of any two clues on a line, climate m= (y2 – y1)/(x2 – x1).
