Linear equation in intercept form is , where is the rate of change and is the - intercept.
The input variable is the number of days and the output variable is the cost.
Change in output values = 25
Change in input values = 1
Rate of change = = = 25
Working backwards with the values in the table, we get (0, 50). So, the -intercept is 50.
So, the linear equation that satisfies the table is = 25 + 50.
Correct Answer is : = 25 + 50
