Someone please tell me what this is, the question is what is the slope of this line ?

Answer: slope ≈0.7
Step-by-step explanation:
The formula for finding the slope of a line is given as :
slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]x_{2}=9[/tex]
[tex]x_{1}=-3[/tex]
[tex]y_{1}= -5[/tex]
[tex]y_{2}= 3.6[/tex]
substituting into the formula we have:
slope = [tex]\frac{3.6-(-5)}{9-(-3)}[/tex]
slope = [tex]\frac{8.6}{12}[/tex]
slope ≈0.7
