Y=mx+b
b=y-intercept (what y is when x is 0)
b= -7
m=slope
m=change in y divided by change in x
m=(y2-y1)/(x2-x1)
m=(17-5)/(4-2)
m=12/2
m=6
Y=mx+b
Y=4x+(-7)
Y=4x-7
The constant is 3.
This is because when x=1, y=3 and when x=2, y=6 so that is a constant change over each interval as seen in the graph which is 3 :)
Using proportions, it is found that the farmer has planted 258 acres.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
He plants 413 acres during the entire year, hence, considering he plants an equal amount daily, and the year is 5/8 over, the amount he has planted is:
A = (5/8) x 413 = 258 acres.
