19.- 20dollars/year 20.-the date is a linear function because it has a constant rate of change 21.-2x+4y=48 22.-x=24 23.-y=12 25.- the x intercept indicates the amount of hotdogs that you can buy when you do not buy any hamburgers 26.- the y intercept indicates the amount of burgers you can buy when x=0
19- The rate of change is $20 dollars per year 20- It DOES represent a linear equation because the rate of change is constant
All now pertains to hamburgers and hotdogs: 21- 2x + 4y = 48 22- x-intercept is 24 23- y-intercept is 12 24- Grqph is either below or above in ,y’a answer 25- the x-intercept is how many hotdogs you could get without buying any hamburgers. 24 hotdogs only 26- the y-intercept is how many hamburgers you could buy without getting any hotdogs. Just 12 hamburgers
