Answer:
4.5 or [tex]\frac{9}{2}[/tex]
Step-by-step explanation:
I selected 2 points on this graph those points being:
(2,9) and (4, 18)
The equation you'd want to use is
[tex]M=\frac{y_2-y_1}{x_2-x_1}[/tex]
so filling in each of the point we'd have this for our equation
[tex]M=\frac{18-9}{4-2}[/tex]
when you do the subtraction for both we'd get
[tex]M=\frac{9}{2}[/tex]
Now if you were asked to get a number instead of a fractions you could divide 9 & 2 and get quotient of 4.5
I hope this helps
