Hello!
The formula used to find the slope of a line can be written as follows:
[tex] \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } [/tex]
Using the table in the image above, we can assume the following:
[tex]Y_{2}[/tex] = 9
[tex]Y_{1} [/tex] = 5
[tex]X_{2} [/tex] = 4
[tex]X_{1} [/tex] = 0
With this knowledge, we can insert all known values into the slope formula above:
[tex] \frac{9-5}{4-0} [/tex]
This expression is the correct answer.
I hope this helps!
