a small dog gets fed 3/4 cup of dog food twice a day. use D for number of days and F for the amount of food in cups, write an equation, relating the variables. use the equation to find how many days a large bag of dog food will last if it contains 210 cups of food.

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
