Determine the constant rate of change (slope) of the linear function. A high school basketball team notices that attendance at i
kolbaska11 [484]

Answer:

The change in the people attending per game is 14.7 times as great as the change in the number of lost games.

This mean every game is lost, 14.7 less people (as the slope is negative) attend the next game.

Step-by-step explanation:

To calculate the slope, we need to relate two points of the function.

The slope m of the function y=m*x+b can be calculated as

We have the point (x=8, y=256) when it says 265 people attended the next game after the team lost 8 games.

The second point is (x=15, y=153) when it says 153 people attended the next game after the team lost 15 games.

We can write

y_2-y_1=(m*x_2+b)-(m*x_1+b)=m*(x_2-x_1)\\\\m=\frac{y_2-y_1}{x_2-x_1} =\frac{256-153}{8-15}=\frac{103}{-7}=  -14.7
