A principal measures the weight of different numbers of textbooks that he finds in a storage room. The scatter plot below shows

Ahat [919]

The slope of the line of best fit is 2.4

Explanation:

To determine the slope of the equation, let us plot the coordinates in the slope form.

Analyzing the graph,some of the points that are on the straight line is (5,12) and (10,24)

Let us use the points (5,12) and (10,24) to find the slope of the line of best fit.

The formula for slope is

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substituting the coordinates (5,12) and (10,24), we have,

$m=\frac{24-12}{10-5}$

Subtracting, we get,

$m=\frac{12}{5}$

Dividing, we have,

$m=2.4$

Hence, The slope of the line of best fit is 2.4

A baseball player hits a ball 360 feet to the outfield. It takes the ball 4 seconds to travel this distance. How many feet does

Nastasia [14]

To answer this we will divide the amount of feet by the amount of seconds. The answer will be the amount of feet the ball travels per second. Lets do it:-

360 / 4 = 90
90 ft per sec.

CHECK OUR WORK:-

90 * 4 = 360
We were RIGHT!!

So, the ball travels 90 feet per sec.

Hope I helped ya!! xD
