Step-by-step explanation:
8 Apples at QuickMart = $1.45
6 Apples at Shop-N-Go = $1.22
Unit rate of Apples at QuickMart = 1.45÷ 8 = $0.18
Unit rate of Apples at Shop-N-Go = $1.22 ÷6 = $0.20
Therefore, buying from QuickMart is better because more Apples at cheaper amount.
Answer:
ŷ = 0.964X1 - 0.336X2 + 13.066
b1 = 0.964 which is the unit change in the value of y when x1 changes.
b2 = - 0.336 which is the unit change in the value of y when x2 changes

The general form of a multiple regression equation is in form:
ŷ = b1x1 + b2x2 + c
Where,
ŷ = predicted or dependent variable
b1 and b2 = slope or gradient Coefficient for the independent or predictor variables x1 and X2 respectively.
c = intercept (constant)
Using the online multiple regression calculator, the model obtained by Inputting the values is written below:
ŷ = 0.964X1 - 0.336X2 + 13.066
Value of b1 = 0.964 which is the unit change in the value of y when x1 changes.
Value b2 = - 0.336 which is the unit change in the value of y when x2 changes
Since the slop of a line is positive, the graph of the line would begin to move upwards, rather than downwards. A graph line only moves downwards when the slope of the line is negative.
the rate of change is +2
Every time the number is given, the number goes up by 2
