5. A baseball team has three different pitchers. Joel pitched 6 innings and allowed 4 runs, Antonio pitched 10 innings and allowed 8 runs, and Francisco pitched 7 innings and allowed 5 runs. Which pitcher has the lowest number of runs allowed per inning? Choose 1 ​

francisco

Step-by-step explanation:

he is only allowed a run every 1.4 innings, while joel is allowed a run every .6 innings and antonion is allowed a run every .8 innings.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
