Answer:
The y-intercept in the model represents the base salary
Step-by-step explanation:
In regression analysis, the y-intercept refers to the point where a regression line crosses or cuts the y-intercept. At this point, the value of the explanatory variable X is usually 0.
In the model, the explanatory variable x is Ashley's total sales for the year. On the other hand the dependent variable is the annual salary which depends on total sales.
Substituting x with 0 in the regression model yields;
y = 0.2(0) + 25,000
y = 25,000
The y-intercept is thus 25,000 which is simply the salary earned in the absence of sales. This is simply the basic salary.

Answer and explanation:
To find : Calculate to the nearest 1/10th foot the length of the side of a 5th, 10th, and 100th acre square plot.
Solution :
The area of the square is given by,
where s is the side length.
We know,
1) The area of square plot is 5 acre.
Area in foot square is
Substitute the value in the formula,
Side nearest to 1/10th foot is 466.7 foot.
2) The area of square plot is 10 acre.
Area in foot square is
Substitute the value in the formula,
Side nearest to 1/10th foot is 660.0 foot.
3) The area of square plot is 100 acre.
Area in foot square is
Substitute the value in the formula,
Side nearest to 1/10th foot is 2087.1 foot.

(a)
The turning point is the vertex of the graph
The coordinates are (2, - 4 )
(b)
The zeros are the values of x where the graph crosses the x- axis
The graph crosses the x- axis at
x = - 1, x = 5 ← zeros
