PLEASEE HELP

Given:

Scatter plot of weight loss plan.

To find:

how many pounds were lost per month with 4 hours of weekly.

Solution:

Take any two points on the trend line.

Let the points are (3, 4) and (5, 7).

Slope of the line:

m = 1.5

Using point-slope formula:

Add 4 on both sides.

Approximate equation of a line is y = 1.5x - 0.5

Substitute x = 4.

y = 1.5(4) - 0.5

y = 6 - 0.5

y = 5.5

Which is nearly equal to 6.

Also see in the scatter plot, y-value for the corresponding value of 4 in x-axis is 6.

Hence 6 pounds lost per month with 4 hours of weekly aerobic activity.
