To find the equation in the form
, we need to determine the slope (m) and the y-intercept (b).Given:- When x = 370, y = 176- When x = 690, y = 304Step 1: Calculate the slope (m)The slope (m) is calculated using the formula:
Substituting the given values:
Step 2: Calculate the y-intercept (b)The equation of a line in slope-intercept form is:
We can use one of the given points to solve for b. Let's use the point (370, 176):
Therefore, the equation in the form
where x is the number of monthly minutes used and y is the total monthly cost of the Ringular plan is:
