Short Answer

Expert verified

The number 6 represents the required slope.

Step by step solution

01

Step 1. Determine the formula that can be used.

The slope formulam=y2鈭�y1x2鈭�x1 can be used to calculate the required slope.

02

Step 2. Take the help of the obtained method.

Take the help of formula for slope of a line represented bym=y2鈭�y1x2鈭�x1in which the required values can be filled by using the provided points as they are in the form of x1,y1x2,y2.

m=14鈭�3423鈭�34=1鈭�348鈭�912=鈭�24鈭�112=鈭�24脳鈭�121=244=6

03

Step 3. Write the conclusion.
