A manufacturer of graphing calculators have determined that 9000 calculations per week will be so that the price of $90 per calculator at a price of $85 it is estimated that 13,000 Kalkulator Kalkulator Sophie’s Eye determine the winner function that predict the number of calculators that will be sold per week at the price of X dollars

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

you are uyytr tyy
