Slope= [tex] \frac{y_2-y_1}{x_2-x_1} [/tex]
We are given two coordinates:
(x1,y1) and (x2,y2)
Plug given numbers into the formula:
[tex] \frac{1-(-3)}{1-(-2)} [/tex]
Two "-"'s next to each other make a positive so we add:
[tex] \frac{1+3=4}{1+2=3} [/tex]
Final answer: D.
Slope= [tex] \frac{4}{3} [/tex]
