that was incorrect

...that was also incorrect

that's still incorrect

that's just the same answer that i said was incorrect

the correct answer was 7.279x + 56.048

b) Now write a linear regression equation for the "fast food" restaurant. y = [ ] (Type an expression using x as the variable. Use integers or decimals for any numbers in the expression. Round to the nearest thousandth as needed.)

this was incorrect
