Answer:
allen= y=3/2+2 billy= y= 3/2+4
Step-by-step explanation:
ok both of the equation are (almost) the same except for the y intercepts.
y=mx+b... you are learning about that hopefully!
so. each of their trees are growing by 3... feet I'll just say feet. that means the slope is three because they are each going up that much. you also have to pay attention to the fact that the year is going up by two, so your tree is actually growing by 1.5 (3 halves) feet each year. now you have to find the y intercept by back tracking. remember that the y intercept is where y is zero and x is whatever it is.
if you go back three on allen, the y intercept is 2 and if you go back on billy, the y intercept is 4.
as for the second question, the lines are parallel. they have the exact same slope so that means that they will never cross because billy's line is higher then allens, billy's tree will always be higher

Answer:
14
Step-by-step explanation:
I would say 14 because if you multiply 8 by 3 it would equal 24. And that is just below 28. Then, I tried to see if 8 x 4 would work, but that equaled 32. And both of those numbers are in between 28. So, if I multiplied 8 by 3 to get 24, I also multiplied the 4 by 3 which equals 12. So, I would say it would be 14.
