For number 6 I’m not sure how to do it

To work out how much a 20lb turkey would cost you have to divide the cost of a 12lb turkey by 12 (15.25/12= 1.27083) as well as dividing the 12lbs by 12 (12/12= 1) then times both numbers by 20 (1.27083 X 20 = 25.42 (rounded)) (1 X 20 = 20) and you have 20lbs turkey=$25.42

25.42 would be the answer

y = - 18

The equation of a line with a slope of zero is a horizontal line, parallel to the x- axis. The equation of this line is y = c , where c is the value of the y- coordinate of a point the line passes through.

here the line passes through (6 , - 18) with y-coordinate of - 18

thus equation is y = - 18
