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

Answer:

$Slope=\frac{7}{2}=3.5$

Step-by-step explanation:

Slope of line: $Slope\ of\ line\ passing\ through\ (x_1,y_1)\ and\ (x_2,y_2)\ is\ given\ by\ \frac{y_2-y_1}{x_2-x_1}$

$Here\ (x_1,y_1)=(\frac{2}{7},5)\\\\(x_2,y_2)=(10,39)\\\\Slope=\frac{39-5}{10-\frac{2}{7}}\\\\Slope=\frac{34}{\frac{68}{7}}\\\\Slope=\frac{34\times 7}{68}\\\\Slope=\frac{7}{2}=3.5$
