Write the equation for the line of best fit
Replace m and b with the value of the slope and the y-intercept, round each number to the nearest tenth

Given:

The given graph shows the scatter points.

We need to determine the equation for the line of best fit.

Slope of the equation:

From the figure, it is obvious that the slope of the line is

Rounding off to the nearest tenth, we get;

Thus, the slope of the equation is

Value of y - intercept:

From the figure, it is obvious that the y - intercept is

Rounding off to the nearest tenth, we get;

Thus, the y - intercept of the equation is

Equation of the line:

The equation of the line can be determined using the formula,

Substituting and , we get;

Thus, the equation for the line of best fit is

y = 2.3x + 33.2

Step-by-step explanation:

Slope: 2.33

Nearest tenth: 2.3

y-intercept: 33.153

Nearest tenth: 33.2

y = 2.3x + 33.2

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
