Question

Help if you do this you will get seven years of good luck if you don't you will get seven years of bad luck: (SAT Prep): Find the slope of the graph using the two lines: A (2/7; 5), B (10;39)

Answer 1

`Slope=(7)/(2)=3.5`

Explanation:

Slope of line:
`Slope\ of\ line\ passing\ through\ (x_1,y_1)\ and\ (x_2,y_2)\ is\ given\ by\ (y_2-y_1)/(x_2-x_1)`

`Here\ (x_1,y_1)=((2)/(7),5)\\\\(x_2,y_2)=(10,39)\\\\Slope=(39-5)/(10-(2)/(7))\\\\Slope=(34)/((68)/(7))\\\\Slope=(34* 7)/(68)\\\\Slope=(7)/(2)=3.5`
