With a certain medical insurance policy, the customer must first pay an annual $250 deductible, and then the policy covers 70% of the cost of x-rays. The first insurance claims for a specific year submitted by a person are for two x-rays. The first x-ray cost $630, and the second x-ray cost $910. How much, in total, will he need to pay for these x-rays?

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

its a, i had the same answer, its from study island right

step-by-step explanation:

answer:

24pi or letter c
