Ineed answers for part 2 of 2 its ut homework on ramps & my hs teacher doesnt go over it

OK. "Linear model" just means a straight-line graph. That's no problem here, because we know two points on the line, and when we know two points, we know (??) how to find the equation of the line.

The equation is going to be

Y = m t + b .

Y is the chicken consumption in pounds

m is the slope of the line

t is the number of years

b is the y-intercept of the line

One point: 1983. t=3, y=30.9 pounds

Other point, 1989: t=9, y=47 pounds

Slope = (47-30.9) / (9-3)

Slope = 16.1/6 = 2.683 pounds per year

Plug that number into the equation for either of the points that we know, and you find that the y-intercept b is 22.85 pounds. So ...

Y = 2.683 t + 22.85 .

(and t is the number of years after 1980)

In 1995, t=15 . Stick that into the equation, and you'll get the estimate for chicken consumption in 1995, IF your model ... based on changes from 1983 to 1989 ... is still accurate for 6 more years after 1989.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

a and b sometimes have a positive value
