Answer:
the slope of the line is 3
Step-by-step explanation:
Hello, I think I can help you with this
if you have two points of a line
[tex]P1=(x_{1},y_{1})\\ and\\P2=(x_{2},y_{2})[/tex]
you can find the slope using
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
Step 1
Let
P1( 1, 3) and P2(3,9)
put the values into the equation
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\m=\frac{9-3}{3-1}\\m=\frac{6}{2}\\ m=3[/tex]
the slope of the line is 3
I hope it helps,Have a great day.
